    LEAR, INC. v. ADKINS, 395 U.S. 653 (1969)

    U.S. Supreme Court

    LEAR, INC. v. ADKINS, 395 U.S. 653 (1969)

    395 U.S. 653

    LEAR, INC. v. ADKINS.
    CERTIORARI TO THE SUPREME COURT OF CALIFORNIA.
    No. 56.
    Argued November 20-21, 1968.
    Decided June 16, 1969.

    Respondent, an engineer and inventor, was hired in 1952 by petitioner (Lear) to help solve gyroscope development problems. They had agreed that "new ideas, discoveries, inventions etc. related to . . . vertical gyros become the property of" respondent, and that the inventor would grant Lear a license as to all ideas he might develop "on a mutually satisfactory royalty basis." Shortly thereafter respondent developed a method for improving gyros which Lear incorporated into its production process. In 1954 respondent filed a patent application covering these improvements and entered into licensing negotiations with Lear to establish a royalty rate. An agreement, concluded in 1955, provided that if the "Patent Office refuses to issue a patent . . . or if such a patent so issued is subsequently held invalid . . . Lear at its option shall have the right forthwith to terminate the specific license so affected or to terminate this entire Agreement . . . ." A patent was issued to respondent in 1960, after several rejections of the application. In 1957 Lear stated that a Patent Office search disclosed a patent which fully anticipated respondent's discovery and that it would no longer pay royalties on the gyros it produced in its Michigan plant, although it continued to pay royalties on gyros produced in its California plant until 1959. Upon receipt of his patent respondent brought suit in the California courts claiming that both the Michigan and California gyros used his patent and that Lear's failure to pay royalties breached the 1955 contract and Lear's quasi-contractual obligations. Although Lear tried to raise patent invalidity as a defense, the trial judge directed a verdict for respondent on the California gyros, holding that Lear was estopped by its licensing agreement from questioning the licensor's patent. Since Lear claimed that it developed its Michigan gyro designs independently of respondent's ideas, the judge instructed the jury to award recovery to the inventor only if it was satisfied that the invention was novel. When the jury returned a substantial verdict for respondent on the Michigan gyros the judge granted Lear's motion for judgment notwithstanding the verdict, finding that the invention had been [395 U.S. 653, 654]   completely anticipated by the prior art. The California Supreme Court held that the 1955 agreement was still in effect, that Lear did not have the right thereunder to terminate its royalty obligations in 1959, and that the doctrine of estoppel barred Lear from questioning the patent. Noting Lear's claim that it had developed the Michigan gyros independently, the court considered "whether what is being built by Lear [in Michigan] springs entirely from the prior art," found that Lear had in fact utilized the patent throughout the period in question, and reinstated the jury's verdict. Held:

      1. Since the California Supreme Court's construction of the 1955 licensing agreement is solely a matter of state law, the only issue open here is raised by the court's reliance on the doctrine of estoppel to bar Lear from contesting the validity of the patent. Pp. 661-662.

      2. In the accommodation of (1) the common law of contracts, and (2) the federal law of patents requiring that all ideas in general circulation be dedicated to the common good unless they are protected by a valid patent, the technical requirements of contract doctrine must yield to the demands of the public interest in the typical situation involving the negotiation of a license after a patent has issued. The holding of Automatic Radio Manufacturing Co. v. Hazeltine Research, Inc., 339 U.S. 827, 836 , that licensee estoppel was "the general rule," is overruled. Pp. 668-671.

      3. Overriding federal policies would be significantly frustrated if licensees could be required to continue to pay royalties while challenging patent validity in the courts, and in this case Lear must be permitted to avoid payment of all royalties accruing after the issuance of the patent if Lear can prove that the patent is invalid. Pp. 671-674.

      4. Respondent's claim to contractual royalties accruing before the issuance of the patent, which raises the question of whether, and to what extent, the States may protect the owners of unpatented inventions who are willing to disclose their ideas only upon the payment of royalties is remanded for specific consideration by the California courts. Pp. 674-675.

      5. It is inappropriate at this time to pass upon Lear's contention that the patent is invalid, as Lear must address its arguments attacking the validity of the underlying patent to the California courts in the first instance. Pp. 675-676.

    67 Cal. 2d 882, 435 P.2d 321, vacated and remanded. [395 U.S. 653, 655]  

    C. Russell Hale argued the cause for petitioner. With him on the briefs were Edwin L. Hartz, Thomas G. Corcoran, and Allen E. Throop.

    Peter R. Cohen argued the cause for respondent. With him on the brief was Allen E. Susman.

    Lawrence G. Wallace argued the cause for the United States as amicus curiae urging reversal. With him on the brief were Solicitor General Griswold, Assistant Attorney General Zimmerman, and Howard E. Shapiro.

    MR. JUSTICE HARLAN delivered the opinion of the Court.

    In January of 1952, John Adkins, an inventor and mechanical engineer, was hired by Lear, Incorporated, for the purpose of solving a vexing problem the company had encountered in its efforts to develop a gyroscope which would meet the increasingly demanding requirements of the aviation industry. The gyroscope is an essential component of the navigational system in all aircraft, enabling the pilot to learn the direction and attitude of his airplane. With the development of the faster airplanes of the 1950's, more accurate gyroscopes were needed, and the gyro industry consequently was casting about for new techniques which would satisfy this need in an economical fashion. Shortly after Adkins was hired, he developed a method of construction at the company's California facilities which improved gyroscope accuracy at a low cost. Lear almost immediately incorporated Adkins' improvements into its production process to its substantial advantage.

    The question that remains unsettled in this case, after eight years of litigation in the California courts, is whether Adkins will receive compensation for Lear's use of those improvements which the inventor has subsequently patented. At every stage of this lawsuit, Lear has sought to prove that, despite the grant of a patent [395 U.S. 653, 656]   by the Patent Office, none of Adkins' improvements were sufficiently novel to warrant the award of a monopoly under the standards delineated in the governing federal statutes. Moreover, the company has sought to prove that Adkins obtained his patent by means of a fraud on the Patent Office. In response, the inventor has argued that since Lear had entered into a licensing agreement with Adkins, it was obliged to pay the agreed royalties regardless of the validity of the underlying patent.

    The Supreme Court of California unanimously vindicated the inventor's position. While the court recognized that generally a manufacturer is free to challenge the validity of an inventor's patent, it held that "one of the oldest doctrines in the field of patent law establishes that so long as a licensee is operating under a license agreement he is estopped to deny the validity of his licensor's patent in a suit for royalties under the agreement. The theory underlying this doctrine is that a licensee should not be permitted to enjoy the benefit afforded by the agreement while simultaneously urging that the patent which forms the basis of the agreement is void." 67 Cal. 2d 882, 891, 435 P.2d 321, 325-326 (1967).

    Almost 20 years ago, in its last consideration of the doctrine, this Court also invoked an estoppel to deny a licensee the right to prove that his licensor was demanding royalties for the use of an idea which was in reality a part of the public domain. Automatic Radio Manufacturing Co. v. Hazeltine Research, Inc., 339 U.S. 827, 836 (1950). We granted certiorari in the present case, 391 U.S. 912 , to reconsider the validity of the Hazeltine rule in the light of our recent decisions emphasizing the strong federal policy favoring free competition in ideas which do not merit patent protection. Sears, Roebuck v. Stiffel Co., 376 U.S. 225 (1964); Compco Corp. v. Day-Brite Lighting, Inc., 376 U.S. 234 (1964). [395 U.S. 653, 657]  

    I.

    At the very beginning of the parties' relationship, Lear and Adkins entered into a rudimentary one-page agreement which provided that although "[a]ll new ideas, discoveries, inventions, etc., related to . . . vertical gyros become the property of Mr. John S. Adkins," the inventor promised to grant Lear a license as to all ideas he might develop "on a mutually satisfactory royalty basis." 1 As soon as Adkins' labors yielded tangible results, it quickly became apparent to the inventor that further steps should be taken to place his rights to his ideas on a firmer basis. On February 4, 1954, Adkins filed an application with the Patent Office in an effort to gain federal protection for his improvements. At about the same time, he entered into a lengthy period of negotiations with Lear in an effort to conclude a licensing agreement which would clearly establish the amount of royalties that would be paid.

    These negotiations finally bore fruit on September 15, 1955, when the parties approved a complex 17-page contract which carefully delineated the conditions upon which Lear promised to pay royalties for Adkins' improvements. The parties agreed that if "the U.S. Patent Office refuses to issue a patent on the substantial claims [contained in Adkins' original patent application] or if such a patent so issued is subsequently held invalid, then in any of such events Lear at its option shall have the right forthwith to terminate the specific license so affected or to terminate this entire Agreement . . . ." 6. (2 App. 138.) [395 U.S. 653, 658]  

    As the contractual language indicates, Adkins had not obtained a final Patent Office decision as to the patentability of his invention at the time the licensing agreement was concluded. Indeed, he was not to receive a patent until January 5, 1960. This long delay has its source in the special character of Patent Office procedures. The regulations do not require the Office to make a final judgment on an invention's patentability on the basis of the inventor's original application. 2 While it sometimes happens that a patent is granted at this early stage, it is far more common for the Office to find that although certain of the applicant's claims may be patentable, certain others have been fully anticipated by the earlier developments in the art. In such a situation, the Patent Office does not attempt to separate the wheat from the chaff on its own initiative. Instead, it rejects the application, giving the inventor the right to make an amendment which narrows his claim to cover only those aspects of the invention which are truly novel. 3 It often happens, however, that even after an application is amended, the Patent Office finds that some of the remaining claims are unpatentable. When this occurs, the agency again issues a rejection which is subject to further amendment. 4 And so the process of rejection and amendment continues until the Patent Office Examiner either grants a patent or concludes that none of the inventor's claims could possibly be patentable, at which time a final rejection is entered on the Office's records. 5 Thus, when Adkins made his original application in 1954, it took the average inventor more than three years before he obtained a final administrative decision on the patentability of his ideas, with the Patent [395 U.S. 653, 659]   Office acting on the average application from two to four times. 6  

    The progress of Adkins' effort to obtain a patent followed the typical pattern. In his initial application, the inventor made the ambitious claim that his entire method of constructing gyroscopes was sufficiently novel to merit protection. The Patent Office, however, rejected this initial claim, as well as two subsequent amendments, which progressively narrowed the scope of the invention sought to be protected. Finally, Adkins narrowed his claim drastically to assert only that the design of the apparatus used to achieve gyroscope accuracy was novel. 7 In response, the Office issued its 1960 patent, granting a 17-year monopoly on this more modest claim.

    During the long period in which Adkins was attempting to convince the Patent Office of the novelty of his ideas, however, Lear had become convinced that Adkins would never receive a patent on his invention and that it should not continue to pay substantial royalties on ideas which had not contributed substantially to the development of the art of gyroscopy. In 1957, after Adkins' patent application had been rejected twice, Lear announced that it had searched the Patent Office's files and had found a patent which it believed had fully anticipated Adkins' discovery. As a result, the company stated that it would no longer pay royalties on the large number of gyroscopes it was producing at its plant in Grand Rapids, Michigan (the Michigan gyros). Payments were continued on the smaller number of gyros produced at the company's [395 U.S. 653, 660]   California plant (the California gyros) for two more years until they too were terminated on April 8, 1959.

    As soon as Adkins obtained his patent in 1960, he brought this lawsuit in the California Superior Court. He argued to a jury that both the Michigan and the California gyros incorporated his patented apparatus and that Lear's failure to pay royalties on these gyros was a breach both of the 1955 contract and of Lear's quasi-contractual obligations. Although Lear sought to raise patent invalidity as a defense, the trial judge directed a verdict of $16,351.93 for Adkins on the California gyros, holding that Lear was estopped by its licensing agreement from questioning the inventor's patent. The trial judge took a different approach when it came to considering the Michigan gyros. Noting that the company claimed that it had developed its Michigan designs independently of Adkins' ideas, the court instructed the jury to award the inventor recovery only if it was satisfied that Adkins' invention was novel, within the meaning of the federal patent laws. When the jury returned a verdict for Adkins of $888,122.56 on the Michigan gyros, 8 the trial judge granted Lear's motion for judgment notwithstanding the verdict, finding that Adkins' invention had been completely anticipated by the prior art. 9   [395 U.S. 653, 661]  

    Neither side was satisfied with this split decision, and both appealed to the California District Court of Appeal, which adopted a quite different approach. The court held that Lear was within its contractual rights in terminating its royalty obligations entirely in 1959, and that if Adkins desired to recover damages after that date he was "relegated to an action for infringement" in the federal courts. 52 Cal. Rptr. 795, 806. So far as pre-1959 royalties were concerned, the court held that the contract required the company to pay royalties on both the California and Michigan gyros regardless of the validity of the inventor's patent. 52 Cal. Rptr., at 809.

    Once again both sides appealed, this time to the California Supreme Court, which took yet another approach to the problem presented. The court rejected the District Court of Appeal's conclusion that the 1955 license gave Lear the right to terminate its royalty obligations in 1959. Since the 1955 agreement was still in effect, the court concluded, relying on the language we have already quoted, that the doctrine of estoppel barred Lear from questioning the propriety of the Patent Office's grant. 67 Cal. 2d, at 907, 435 P.2d, at 336. The court's adherence to estoppel, however, was not without qualification. After noting Lear's claim that it had developed its Michigan gyros independently, the court tested this contention by considering "whether what is being built by Lear [in Michigan] springs entirely" (emphasis supplied) from the prior art. 67 Cal. 2d, at 913, 435 P.2d, at 340. Applying this test, it found that Lear had in fact "utilized the apparatus patented by Adkins throughout the period in question," 67 Cal. 2d, at 915, 435 P.2d, at 341, and reinstated the jury's $888,000 verdict on this branch of the case.

    II.

    Since the California Supreme Court's construction of the 1955 licensing agreement is solely a matter of state [395 U.S. 653, 662]   law, the only issue open to us is raised by the court's reliance upon the doctrine of estoppel to bar Lear from proving that Adkins' ideas were dedicated to the common welfare by federal law. 10 In considering the propriety of the State Court's decision, we are well aware that we are not writing upon a clean slate. The doctrine of estoppel has been considered by this Court in a line of cases reaching back into the middle of the 19th century. Before deciding what the role of estoppel [395 U.S. 653, 663]   should be in the present case and in the future, it is, then, desirable to consider the role it has played in the past.

    A.

    While the roots of the doctrine have often been celebrated in tradition, we have found only one 19th century case in this Court that invoked estoppel in a considered manner. And that case was decided before the Sherman Act made it clear that the grant of monopoly power to a patent owner constituted a limited exception to the general federal policy favoring free competition. Kinsman v. Parkhurst, 18 How. 289 (1856). 11 Curiously, a second decision often cited as supporting the estoppel doctrine points clearly in the opposite direction. St. Paul Plow Works v. Starling, 140 U.S. 184 (1891), did not even question the right of the lower courts to admit the licensee's evidence showing that the patented device was not novel. A unanimous Court merely held that, where there was conflicting evidence as to an invention's novelty, it would not reverse the decision of the lower court upholding the patent's validity.

    In the very next year, this Court found the doctrine of patent estoppel so inequitable that it refused to grant an injunction to enforce a licensee's promise never to contest the validity of the underlying patent. "It is as [395 U.S. 653, 664]   important to the public that competition should not be repressed by worthless patents, as that the patentee of a really valuable invention should be protected in his monopoly . . . ." Pope Manufacturing Co. v. Gormully, 144 U.S. 224, 234 (1892).

    Although this Court invoked an estoppel in 1905 without citing or considering Pope's powerful argument, United States v. Harvey Steel Co., 196 U.S. 310 , the doctrine was not to be applied again in this Court until it was revived in Automatic Radio Manufacturing Co. v. Hazeltine Research, Inc., supra, which declared, without prolonged analysis, that licensee estoppel was "the general rule." 339 U.S., at 836 . In so holding, the majority ignored the teachings of a series of decisions this Court had rendered during the 45 years since Harvey had been decided. During this period, each time a patentee sought to rely upon his estoppel privilege before this Court, the majority created a new exception to permit judicial scrutiny into the validity of the Patent Office's grant. Long before Hazeltine was decided, the estoppel doctrine had been so eroded that it could no longer be considered the "general rule," but was only to be invoked in an ever-narrowing set of circumstances.

    B.

    The estoppel rule was first stringently limited in a situation in which the patentee's equities were far more compelling than those presented in the typical licensing arrangement. Westinghouse Electric & Manufacturing Co. v. Formica Insulation Co., 266 U.S. 342 (1924), framed a rule to govern the recurring problem which arises when the original patent owner, after assigning his patent to another for a substantial sum, claims that the patent is worthless because it contains no new ideas. The courts of appeals had traditionally refused to permit such a defense to an infringement action on the ground [395 U.S. 653, 665]   that it was improper both to "sell and keep the same thing." Faulks v. Kamp, 3 F. 898, 902 (1880). Nevertheless, Formica imposed a limitation upon estoppel which was radically inconsistent with the premises upon which the "general rule" is based. The Court held that while an assignor may not directly attack the validity of a patent by reference to the prior state of the art, he could introduce such evidence to narrow the claims made in the patent. "The distinction may be a nice one but seems to be workable." 266 U.S., at 351 . Workable or not, the result proved to be an anomaly: if a patent had some novelty Formica permitted the old owner to defend an infringement action by showing that the invention's novel aspects did not extend to the inclusion of the old owner's products; on the other hand, if a patent had no novelty at all, the old owner could not defend successfully since he would be obliged to launch the direct attack on the patent that Formica seemed to forbid. The incongruity of this position compelled at least one court of appeals to carry the reasoning of the Formica exception to its logical conclusion. In 1940 the Seventh Circuit held that a licensee could introduce evidence of the prior art to show that the licensor's claims were not novel at all and thus successfully defend an action for royalties. Casco Products Corp. v. Sinko Tool & Manufacturing Co., 116 F.2d 119.

    In Scott Paper Co. v. Marcalus Manufacturing Co., 326 U.S. 249 (1945), this Court adopted a position similar to the Seventh Circuit's, undermining the basis of patent estoppel even more than Formica had done. In Scott, the original patent owner had attempted to defend an infringement suit brought by his assignee by proving that his product was a copy of an expired patent. The Court refused to permit the assignee to invoke an estoppel, finding that the policy of the patent laws would be frustrated if a manufacturer was required to pay for the use of information which, under the patent statutes, was [395 U.S. 653, 666]   the property of all. Chief Justice Stone, for the Court, did not go beyond the precise question presented by a manufacturer who asserted that he was simply copying an expired patent. Nevertheless it was impossible to limit the Scott doctrine to such a narrow compass. If patent policy forbids estoppel when the old owner attempts to show that he did no more than copy an expired patent, why should not the old owner also be permitted to show that the invention lacked novelty because it could be found in a technical journal or because it was obvious to one knowledgeable in the art? As Justice Frankfurter's dissent indicated, id., at 258-264, there were no satisfactory answers to these questions. The Scott exception had undermined the very basis of the "general rule."

    C.

    At about the time Scott was decided, this Court developed yet another doctrine which was profoundly antithetic to the principles underlying estoppel. In Sola Electric Co. v. Jefferson Electric Co., 317 U.S. 173 (1942), the majority refused to permit a licensor to enforce the license's price-fixing provisions without permitting the licensee to contest the validity of the underlying patent. Since the price-fixing clause was per se illegal but for the existence of a valid patent, this narrow exception could be countenanced without compromising the general estoppel principle. But the Sola Court went further: it held that since the patentee had sought to enforce the price-fixing clause, the licensee could also avoid paying royalties if he could show that the patent was invalid. Five years later, the "anti-trust exception" was given an even more extensive scope in the Katzinger and MacGregor cases. 12 Here, licensors [395 U.S. 653, 667]   were not permitted to invoke an estoppel despite the fact that they sought only to collect their royalties. The mere existence of a price-fixing clause in the license was held to be enough to bring the validity of the patent into question. Thus in the large number of cases in which licensing agreements contained restrictions that were arguably illegal under the antitrust laws, the doctrine of estoppel was a dead letter. Justice Frankfurter, in dissent, went even further, concluding that Katzinger and MacGregor had done all but repudiate the estoppel rule: "If a doctrine that was vital law for more than ninety years will be found to have now been deprived of life, we ought at least to give it decent public burial." 329 U.S., at 416 .

    D.

    The lower courts, both state and federal, have also hedged the impact of estoppel by creating exceptions which have indicated a recognition of the broader policies pointing to a contrary approach. It is generally the rule that licensees may avoid further royalty payments, regardless of the provisions of their contract, once a third party proves that the patent is invalid. See, e. g., Drackett Chemical Co. v. Chamberlain Co., 63 F.2d 853 (1933). Some courts have gone further to hold that a licensee may notify the patent owner that he is repudiating his agreement, regardless of its terms, and may subsequently defend any action for royalties by proving patent invalidity. Note, The Doctrine of Licensee Repudiation in Patent Law, 63 Yale L. J. 125 (1953); R. Ellis, Patent Licenses 328 (3d ed., A. Deller 1958). And even in the 19th century, state courts had held that if the licensee had not actually sold products incorporating the patent's ideas, he could challenge the validity of the patent. See Forkosch, Licensee [395 U.S. 653, 668]   Estoppel in Patent Law, 20 Temp. L. Q. 515, 529, n. 45 (1947). 13  

    III.

    The uncertain status of licensee estoppel in the case law is a product of judicial efforts to accommodate the competing demands of the common law of contracts and the federal law of patents. On the one hand, the law of contracts forbids a purchaser to repudiate his promises simply because he later becomes dissatisfied with the bargain he has made. 14 On the other hand, federal law requires that all ideas in general circulation be dedicated to the common good unless they are protected by a valid patent. Sears, Roebuck v. Stiffel Co., supra; Compco Corp. v. Day-Brite Lighting, Inc., supra. When faced with this basic conflict in policy, both this Court and courts throughout the land have naturally sought to develop an intermediate position which somehow would remain responsive to the radically different concerns of the two different worlds of contract and patent. The result has been a failure. Rather than creative compromise, there has been a chaos of conflicting case law, proceeding on inconsistent premises. Before renewing the search for an acceptable middle ground, we must reconsider on their own merits the arguments which may properly be advanced on both sides of the estoppel question. [395 U.S. 653, 669]  

    A.

    It will simplify matters greatly if we first consider the most typical situation in which patent licenses are negotiated. In contrast to the present case, most manufacturers obtain a license after a patent has issued. Since the Patent Office makes an inventor's ideas public when it issues its grant of a limited monopoly, 15 a potential licensee has access to the inventor's ideas even if he does not enter into an agreement with the patent owner. Consequently, a manufacturer gains only two benefits if he chooses to enter a licensing agreement after the patent has issued. First, by accepting a license and paying royalties for a time, the licensee may have avoided the necessity of defending an expensive infringement action during the period when he may be least able to afford one. Second, the existence of an unchallenged patent may deter others from attempting to compete with the licensee. 16  

    Under ordinary contract principles the mere fact that some benefit is received is enough to require the enforcement of the contract, regardless of the validity of the underlying patent. Nevertheless, if one tests this result by the standard of good-faith commercial dealing, it seems far from satisfactory. For the simple contract approach entirely ignores the position of the licensor who is seeking to invoke the court's assistance on his behalf. Consider, for example, the equities of the licensor who has obtained his patent through a fraud on the Patent Office. It is difficult to perceive why good [395 U.S. 653, 670]   faith requires that courts should permit him to recover royalties despite his licensee's attempts to show that the patent is invalid. Compare Walker Process Equipment, Inc. v. Food Machinery & Chemical Corp., 382 U.S. 172 (1965).

    Even in the more typical cases, not involving conscious wrongdoing, the licensor's equities are far from compelling. A patent, in the last analysis, simply represents a legal conclusion reached by the Patent Office. Moreover, the legal conclusion is predicated on factors as to which reasonable men can differ widely. Yet the Patent Office is often obliged to reach its decision in an ex parte proceeding, without the aid of the arguments which could be advanced by parties interested in proving patent invalidity. Consequently, it does not seem to us to be unfair to require a patentee to defend the Patent Office's judgment when his licensee places the question in issue, especially since the licensor's case is buttressed by the presumption of validity which attaches to his patent. Thus, although licensee estoppel may be consistent with the letter of contractual doctrine, we cannot say that it is compelled by the spirit of contract law, which seeks to balance the claims of promisor and promisee in accord with the requirements of good faith.

    Surely the equities of the licensor do not weigh very heavily when they are balanced against the important public interest in permitting full and free competition in the use of ideas which are in reality a part of the public domain. Licensees may often be the only individuals with enough economic incentive to challenge the patentability of an inventor's discovery. If they are muzzled, the public may continually be required to pay tribute to would-be monopolists without need or justification. We think it plain that the technical requirements of contract doctrine must give way before the demands of the public interest in the typical situation [395 U.S. 653, 671]   involving the negotiation of a license after a patent has issued.

    We are satisfied that Automatic Radio Manufacturing Co. v. Hazeltine Research, Inc., supra, itself the product of a clouded history, should no longer be regarded as sound law with respect to its "estoppel" holding, and that holding is now overruled.

    B.

    The case before us, however, presents a far more complicated estoppel problem than the one which arises in the most common licensing context. The problem arises out of the fact that Lear obtained its license in 1955, more than four years before Adkins received his 1960 patent. Indeed, from the very outset of the relationship, Lear obtained special access to Adkins' ideas in return for its promise to pay satisfactory compensation.

    Thus, during the lengthy period in which Adkins was attempting to obtain a patent, Lear gained an important benefit not generally obtained by the typical licensee. For until a patent issues, a potential licensee may not learn his licensor's ideas simply by requesting the information from the Patent Office. During the time the inventor is seeking patent protection, the governing federal statute requires the Patent Office to hold an inventor's patent application in confidence. 17 If a potential [395 U.S. 653, 672]   licensee hopes to use the ideas contained in a secret patent application, he must deal with the inventor himself, unless the inventor chooses to publicize his ideas to the world at large. By promising to pay Adkins royalties from the very outset of their relationship, Lear gained immediate access to ideas which it may well not have learned until the Patent Office published the details of Adkins' invention in 1960. At the core of this case, then, is the difficult question whether federal patent policy bars a State from enforcing a contract regulating access to an unpatented secret idea. 18  

    Adkins takes an extreme position on this question. The inventor does not merely argue that since Lear obtained privileged access to his ideas before 1960, the company should be required to pay royalties accruing before 1960 regardless of the validity of the patent which ultimately issued. He also argues that since Lear obtained special benefits before 1960, it should also pay royalties during the entire patent period (1960-1977), without regard to the validity of the Patent Office's grant. We cannot accept so broad an argument.

    Adkins' position would permit inventors to negotiate all important licenses during the lengthy period while their applications were still pending at the Patent Office, thereby disabling entirely all those who have the strongest incentive to show that a patent is worthless. While the equities supporting Adkins' position are somewhat more appealing than those supporting the typical [395 U.S. 653, 673]   licensor, we cannot say that there is enough of a difference to justify such a substantial impairment of overriding federal policy.

    Nor can we accept a second argument which may be advanced to support Adkins' claim to at least a portion of his post-patent royalties, regardless of the validity of the Patent Office grant. The terms of the 1955 agreement provide that royalties are to be paid until such time as the "patent . . . is held invalid," 6, and the fact remains that the question of patent validity has not been finally determined in this case. Thus, it may be suggested that although Lear must be allowed to raise the question of patent validity in the present lawsuit, it must also be required to comply with its contract and continue to pay royalties until its claim is finally vindicated in the courts.

    The parties' contract, however, is no more controlling on this issue than is the State's doctrine of estoppel, which is also rooted in contract principles. The decisive question is whether overriding federal policies would be significantly frustrated if licensees could be required to continue to pay royalties during the time they are challenging patent validity in the courts.

    It seems to us that such a requirement would be inconsistent with the aims of federal patent policy. Enforcing this contractual provision would give the licensor an additional economic incentive to devise every conceivable dilatory tactic in an effort to postpone the day of final judicial reckoning. We can perceive no reason to encourage dilatory court tactics in this way. Moreover, the cost of prosecuting slow-moving trial proceedings and defending an inevitable appeal might well deter many licensees from attempting to prove patent invalidity in the courts. The deterrent effect would be particularly severe in the many scientific fields in which invention is proceeding at a rapid rate. In these areas, a patent may well become obsolete long before its [395 U.S. 653, 674]   17-year term has expired. If a licensee has reason to believe that he will replace a patented idea with a new one in the near future, he will have little incentive to initiate lengthy court proceedings, unless he is freed from liability at least from the time he refuses to pay the contractual royalties. Lastly, enforcing this contractual provision would undermine the strong federal policy favoring the full and free use of ideas in the public domain. For all these reasons, we hold that Lear must be permitted to avoid the payment of all royalties accruing after Adkins' 1960 patent issued if Lear can prove patent invalidity. 19  

    C.

    Adkins' claim to contractual royalties accruing before the 1960 patent issued is, however, a much more difficult one, since it squarely raises the question whether, and to what extent, the States may protect the owners of unpatented inventions who are willing to disclose their ideas to manufacturers only upon payment of royalties. The California Supreme Court did not address itself to this issue with precision, for it believed that the venerable doctrine of estoppel provided a sufficient answer to all of Lear's claims based upon federal patent law. Thus, we do not know whether the Supreme Court would have awarded Adkins recovery even on his pre-patent royalties if it had recognized that previously established estoppel doctrine could no longer be properly invoked [395 U.S. 653, 675]   with regard to royalties accruing during the 17-year patent period. Our decision today will, of course, require the state courts to reconsider the theoretical basis of their decisions enforcing the contractual rights of inventors and it is impossible to predict the extent to which this re-evaluation may revolutionize the law of any particular State in this regard. Consequently, we have concluded, after much consideration, that even though an important question of federal law underlies this phase of the controversy, we should not now attempt to define in even a limited way the extent, if any, to which the States may properly act to enforce the contractual rights of inventors of unpatented secret ideas. Given the difficulty and importance of this task, it should be undertaken only after the state courts have, after fully focused inquiry, determined the extent to which they will respect the contractual rights of such inventors in the future. Indeed, on remand, the California courts may well reconcile the competing demands of patent and contract law in a way which would not warrant further review in this Court.

    IV.

    We also find it inappropriate to pass at this time upon Lear's contention that Adkins' patent is invalid.

    Not only did Lear fail to raise this issue in its petition for certiorari, but the California Supreme Court has yet to pass on the question of patent validity in that clear and unequivocal manner which is so necessary for proper adjudication in this Court. As we have indicated, the California Supreme Court considered the novelty of Adkins' ideas relevant to its decision at only one stage of its extensive analysis. Since Lear claimed that it had developed its Michigan gyros completely independently of Adkins' efforts, the Supreme Court believed itself obliged to consider whether Adkins' ideas were not "entirely" anticipated by the prior art. 67 Cal. 2d, at 913, 435 P.2d, at 340. Applying [395 U.S. 653, 676]   this test, the court upheld the jury's verdict of $888,000 on the Michigan gyros, finding that "Lear utilized the apparatus patented by Adkins throughout the period in question." 67 Cal. 2d, at 915, 435 P.2d, at 341. In reaching this conclusion, however, the court did express its belief that Adkins' invention made a "significant step forward" in the art of gyroscopy. 67 Cal. 2d, at 915, 435 P.2d, at 341.

    It is far from clear that the court, in making this last statement, intended to hold that Adkins' ideas satisfied the demanding standard of invention explicated in our decision in Graham v. John Deere Co., 383 U.S. 1 (1966). Surely, such a holding was not required by the court's analysis, which was concerned only with the question whether Lear had benefited from Adkins' ideas in any degree. In this context, we believe that Lear must be required to address its arguments attacking the validity of the underlying patent to the California courts in the first instance.

    The judgment of the Supreme Court of California is vacated and the case is remanded to that court for further proceedings not inconsistent with this opinion.

      It is so ordered.

    Footnotes

    [ Footnote 1 ] Lear argues that this original agreement was not submitted in evidence at trial and so should not be considered a part of the record on appeal. The California Supreme Court, however, treated the agreement as an important part of the record before it, 67 Cal. 2d, at 906, 435 P.2d, at 335; and so we are free to refer to it.

    [ Footnote 2 ] 37 CFR 1.111 (1967).

    [ Footnote 3 ] 37 CFR 1.106 (1967).

    [ Footnote 4 ] 37 CFR 1.112 (1967).

    [ Footnote 5 ] 37 CFR 1.113 (1967).

    [ Footnote 6 ] A. Seidel, What the General Practitioner Should Know About Patent Law and Practice 61 (A. L. I. 1956).

    [ Footnote 7 ] Adkins actually amended his application a third time before he made the amendment which gained the approval of the Patent Office. This third amendment was superseded by the successful amendment, however, before the Patent Office considered it.

    [ Footnote 8 ] For purposes of the present lawsuit, the parties stipulated that the jury would award only those damages accruing before May 31, 1963.

    [ Footnote 9 ] Adkins also filed a second cause of action which contended that Lear had wrongfully appropriated a valuable trade secret and so was liable regardless of the validity of the inventor's contractual and quasi-contractual theories. The trial court, however, required Adkins to choose between his contract and tort claims. Since the California Supreme Court completely vindicated the inventor's right to contractual royalties, it was not obliged to consider the propriety of this aspect of the trial judge's decision. Consequently, the tort claim is not before us at this time.

    [ Footnote 10 ] Adkins claims that we have no jurisdiction to decide the federal question presented because the company did not adequately preserve it in its argument before the State Supreme Court. We do not agree. While it is true that Lear did not ask the Supreme Court to repudiate estoppel entirely, it did seek to persuade the court to carve out an exception to the estoppel principle which was so sweeping as to undermine the doctrine's vitality completely. The company argued, on the basis of federal as well as state cases, that a licensee may escape the impact of estoppel simply by announcing that it has repudiated the licensing agreement, regardless of the contract's terms. See, e. g., Respondent's and Cross-Appellant's Opening Brief in Cases Nos. 28624 and 30089, at 110-111.

    The California Supreme Court rejected this argument on its merits:

      "Lear relies on authorities holding that a licensee may terminate a license agreement upon notice to his licensor even though, prior to termination, there has been no adjudication of invalidity of the patent which is the subject of the agreement and that thereafter the licensee may challenge the validity of the patent. (See, e. g., Armstrong Co. v. Shell Co. of Cal. (1929) 98 Cal. App. 769, 778-779). This rule has no application if the agreement sets forth the particular circumstances under which termination must occur. As stated above, such provisions must be complied with in order to effect a valid cancellation." 67 Cal. 2d, at 899-900 n. 15, 435 P.2d, at 331, n. 15.

    We clearly have jurisdiction to consider whether this decision is wrong. In doing so, we have the duty to consider the broader implications of Lear's contention, and vindicate, if appropriate, its claim to relief on somewhat different grounds than it chose to advance below, especially when the California court recognized, in language we have already quoted, supra, at 656, that matters of basic principle are at stake.

    [ Footnote 11 ] There are two other early cases which enforced patent licenses without a thorough consideration of the estoppel issues that were presented. In Eureka Co. v. Bailey Co., 11 Wall. 488 (1871), the Court held that a licensee was obliged to overcome a "very strong presumption" of patent validity in order to avoid his royalty obligations, without indicating how much more compelling a showing was required than was considered necessary in an ordinary infringement action. In Dale Tile Manufacturing Co. v. Hyatt, 125 U.S. 46 (1888), this Court affirmed the decision of the New York state courts invoking the doctrine of licensee estoppel, on the ground that the estoppel question presented was one which involved only state law.

    [ Footnote 12 ] Edward Katzinger Co. v. Chicago Metallic Manufacturing Co., 329 U.S. 394 (1947); MacGregor v. Westinghouse Electric & Manufacturing Co., 329 U.S. 402 (1947).

    [ Footnote 13 ] In addition to the works cited in the text, a detailed explication of the development of estoppel doctrine may be found in Cooper, Estoppel to Challenge Patent Validity: The Case of Private Good Faith vs. Public Policy, 18 W. Res. L. Rev. 1122 (1967), and in Kramer, Estoppel To Deny Validity - A Slender Reed, 23 N. Y. U. Intra. L. Rev. 237 (1968).

    [ Footnote 14 ] See 1 A. Corbin, Contracts 127 (1963); Treece, Licensee Estoppel in Patent and Trademark Cases, 53 Iowa L. Rev. 525, 528-530 (1967).

    [ Footnote 15 ] 37 CFR 1.11, 1.13 (1967).

    [ Footnote 16 ] Of course, the value of this second benefit may depend upon whether the licensee has obtained exclusive or nonexclusive rights to the use of the patent. Even in the case of nonexclusive licenses, however, competition is limited to the extent that the royalty charged by the patentee serves as a barrier to entry.

    [ Footnote 17 ] 35 U.S.C. 122 provides:

      "Applications for patents shall be kept in confidence by the Patent Office and no information concerning the same given without authority of the applicant or owner unless necessary to carry out the provisions of any Act of Congress or in such special circumstances as may be determined by the Commissioner."

    The present regulations issued by the Patent Office unequivocally guarantee that: "Pending patent applications are preserved in secrecy . . . unless it shall be necessary to the proper conduct of business before the Office" to divulge their contents. 37 CFR [395 U.S. 653, 672]   1.14 (a) (1967). The parties do not contend that Adkins' patent application was publicized by the Office during the period it was under consideration.

    [ Footnote 18 ] See Doerfer, The Limits on Trade Secret Law Imposed by Federal Patent and Antitrust Supremacy, 80 Harv. L. Rev. 1432 (1967); Note, The Stiffel Doctrine and the Law of Trade Secrets, 62 Nw. U. L. Rev. 956 (1968); Adelman, Trade Secrets and Federal Pre-emption - the Aftermath of Sears and Compco, 49 J. Pat. Off. Soc. 713 (1967); Treece, Patent Policy and Preemption: The Stiffel and Compco Cases, 32 U. Chi. L. Rev. 80 (1964).

    [ Footnote 19 ] Adkins suggests that any decision repudiating licensee estoppel as the general rule should not be retroactively applied to contracts concluded before such a decision is announced. Given the extent to which the estoppel principle had been eroded by our prior decisions, we believe it clear that the patent owner - even before this decision - could not confidently rely upon the continuing vitality of the doctrine. Nor can we perceive that our decision today is likely to undermine any existing legitimate business relationships. Moreover, the public's interest in the elimination of specious patents would be significantly prejudiced if the retroactive effect of today's decision were limited in any way.

    MR. JUSTICE BLACK, with whom THE CHIEF JUSTICE and MR. JUSTICE DOUGLAS join, concurring in part and dissenting in part.

    I concur in the judgment and opinion of the Court, except for what is said in Part III, C, of the Court's opinion. What the Court does in this part of its opinion is to reserve for future decision the question whether the States have power to enforce contracts under which someone claiming to have a new discovery can obtain payment for disclosing it while his patent application is pending, even though the discovery is later held to be unpatentable. This reservation is, as I see it, directly [395 U.S. 653, 677]   in conflict with what this Court held to be the law in Sears, Roebuck v. Stiffel Co., 376 U.S. 225 (1964), and Compco Corp. v. Day-Brite Lighting, Inc., 376 U.S. 234 (1964). Brother HARLAN concurred in the result in those cases, saying - contrary to what the Court held - "I see no reason why the State may not impose reasonable restrictions on the future `copying' itself." Compco, supra, at 239. Consequently the Court is today joining in the kind of qualification that only MR. JUSTICE HARLAN was willing to make at the time of our Stiffel and Compco decisions.

    I still entertain the belief I expressed for the Court in Stiffel and Compco that no State has a right to authorize any kind of monopoly on what is claimed to be a new invention, except when a patent has been obtained from the Patent Office under the exacting standards of the patent laws. One who makes a discovery may, of course, keep it secret if he wishes, but private arrangements under which self-styled "inventors" do not keep their discoveries secret, but rather disclose them, in return for contractual payments, run counter to the plan of our patent laws, which tightly regulate the kind of inventions that may be protected and the manner in which they may be protected. The national policy expressed in the patent laws, favoring free competition and narrowly limiting monopoly, cannot be frustrated by private agreements among individuals, with or without the approval of the State.

    MR. JUSTICE WHITE, concurring in part.

    The applicable provision of 28 U.S.C. 1257 empowers us to review by writ of certiorari "[f]inal judgments or decrees rendered by the highest court of a State . . . where any title, right, privilege or immunity is specially set up or claimed under the Constitution, treaties or statutes of, or commission held or authority exercised under, the [395 U.S. 653, 678]   United States." Although Adkins disputes it, we have jurisdiction to consider whether a patent licensee is estopped to challenge the validity of the patent. The California Supreme Court ruled that he is and therefore would not entertain attacks on Adkins' patent as a defense to his suit for royalties. Lear seeks review of that holding here. In my view, not only is the issue properly here but the Court has correctly decided it.

    Although we have jurisdiction to review this state court judgment and to determine the licensee estoppel issue, it does not necessarily follow that we may or should deal with two other federal questions which come into focus once the licensee is free to challenge the patent. The first is whether the patent is valid. The second, which arises only if the patent is invalidated, is whether federal law forbids the collection of royalties which might otherwise be collectible under a contract rooted in state law. Although the Court does not deal with the first issue, it does purport to decide the second, at least in part. However, as either a jurisdictional or a policy matter, neither of these issues is properly before us in this case.

    In the first place, we have no decision of the California Supreme Court affirming or denying, as a matter of federal law, that Adkins may not enforce his contract if his patent is held invalid. The California court held that the license agreement had not been terminated in accordance with its terms, that the doctrine of licensee estoppel prevented Lear from challenging the patent and that Lear was utilizing the teaching of Adkins' patent. There was thus no necessity or reason to consider whether the patent was invalid, or, if it was, whether either state or federal law prevented collection of the royalties reserved by the contract. Even if these issues had been presented to the California Supreme Court, sound principles would have dictated that the court not render a [395 U.S. 653, 679]   decision on questions unnecessary to its disposition of the case. See, e. g., Southwestern Bell Telephone Co. v. Oklahoma, 303 U.S. 206, 212 -213 (1938).

    There is no indication, however, that Lear, directly or by inference, urged in the California courts that if Adkins' patent were invalid, federal law overrode state contract law and precluded collection of the royalties which Lear had promised to pay. One of the defenses presented by Lear in its answer to Adkins' claim for royalties was that there had been a failure of consideration because of the absence of bargained-for patent-ability in Adkins' ideas. But failure of consideration is a state law question, and I find nothing in the record and nothing in this Court's opinion indicating that Lear at any time contended in the state courts that once Adkins' patent was invalidated, the royalty agreement was unenforceable as a matter of federal law. 1  

    Given Lear's failure below to "specially set up or claim" the federal bar to collection of royalties in the [395 U.S. 653, 680]   event Adkins' patent was invalidated, and without the California Supreme Court's "final judgment" on this issue, I doubt our jurisdiction to decide the issue. But even if jurisdiction exists, the Court should follow its characteristic practice and refuse to issue pronouncements on questions not urged or decided in the state courts.

    In McGoldrick v. Compagnie Generale Transatlantique, 309 U.S. 430 (1940), the Court, while recognizing it had jurisdiction to determine whether a New York tax was an unconstitutional burden on interstate commerce, refused to consider whether the tax was a prohibited impost or duty on imports and exports, saying: "[I]t is only in exceptional cases, and then only in cases coming from the federal courts, that [the Court] considers questions urged by a petitioner or appellant not pressed or passed upon in the courts below. . . . [D]ue regard for the appropriate relationship of this Court to state courts requires us to decline to consider and decide questions affecting the validity of state statutes not urged or considered there." Id., at 434.

    Wilson v. Cook, 327 U.S. 474 (1946), reached a similar conclusion. There the Court denied a government contractor the benefit of the implied constitutional immunity of the Federal Government from taxation by the State, but at the same time declined to consider whether the state tax at issue placed a forbidden tax directly on the United States. This was because the Court was "not free to consider" a ground of attack "not presented to the Supreme Court of Arkansas or considered or decided by it," even though the issue was in some measure related to one actually decided by the state courts and arose under the same implied constitutional immunity argument. Id., at 483. Cf. Dewey v. Des Moines, 173 U.S. 193, 197 -198 (1899). The Court relied on McGoldrick and a long line of prior cases, including New York ex rel. Cohn v. Graves, 300 U.S. 308, 317 (1937), [395 U.S. 653, 681]   where the Court had said: "In reviewing the judgment of a state court, this Court will not pass upon any federal question not shown by the record to have been raised in the state court or considered there, whether it be one arising under a different or the same clause in the Constitution with respect to which other questions are properly presented."

    The result is the same when a party has attempted to raise an issue in the state court but has not done so in proper or timely fashion. "Questions first presented to the highest State court on a petition for rehearing come too late for consideration here . . . ." Radio Station WOW v. Johnson, 326 U.S. 120, 128 (1945). "Since the State Supreme Court did not pass on the question now urged, and since it does not appear to have been properly presented to that court for decision, we are without jurisdiction to consider it in the first instance here." CIO v. McAdory, 325 U.S. 472, 477 (1945). And no different conclusion obtains when the federal question, although not yet presented to or decided by the state court, will probably or even certainly arise during further proceedings held in that court. See, e. g., NAACP v. Alabama, 357 U.S. 449, 466 -467 (1958); Hudson Distributors, Inc. v. Eli Lilly & Co., 377 U.S. 386, 394 -395 (1964).

    Wholly aside from jurisdictional considerations or those relating to our relationships with state courts, there is the matter of our own Rule 23 (1) (c), which states that "[o]nly the questions set forth in the petition or fairly comprised therein will be considered by the court." See Flournoy v. Wiener, 321 U.S. 253, 259 (1944). None of the questions presented by Lear's petition for certiorari comes even close to the issue to which the Court now addresses itself - an issue which will arise only if Lear can and does challenge the patent, if the patent is declared invalid, if Adkins nevertheless seeks to enforce the agreement, and if Lear interposes a defense based on federal law. [395 U.S. 653, 682]  

    This seems a poor case for waiving our Rules. In the first place, the question of validity has not been reached by the California Supreme Court, and when it is the patent may withstand attack. In that event there will be no necessity to consider the impact of patent law on the enforceability of a contract grounded in state law. Second, even if the patent is declared invalid, the state court, after the parties have addressed themselves to the issues, may accommodate federal and state law in a matter which would not prompt review here. Third, the parties themselves have neither briefed nor seriously argued the question in this Court, and we do not have the benefit of their views on what is surely a difficult question. The Court itself has flushed the issue, which it now deals with on a piecemeal basis. 2 Like the question of patent validity, I would leave the consequences of invalidity to the state court in the first instance.

    [ Footnote 1 ] The Court brushes aside the problem by characterizing the additional issue it decides as representing a "more complicated estoppel problem." But licensee estoppel, the question raised here, refers to estoppel against the licensee to challenge the patent, not to any bar or "estoppel" interposed by federal law against collecting royalties on an invalidated patent. Whether Adkins can enforce his contract for royalties if his patent is found to be invalid cannot be shoehorned into the licensee-estoppel question, and by no stretch of the imagination can it be included within the scope of the question raised and litigated by the parties in this case. In the courts below Lear wanted to challenge Adkins' patent only for the purpose of showing that Adkins was entitled to no recovery under the terms of the contract itself, either because of a failure of consideration or because the contract had been legally terminated or could be legally terminated. Indeed, the District Court of Appeal noted: "Lear concedes that it would be estopped to contest the validity of any patent issued to Adkins on the claims of his application described in the license agreement so long as it continued to operate under that agreement." 52 Cal. Rptr. 795, 805. See also Lear's Opening Brief in the District Court of Appeal 109.

    [ Footnote 2 ] The Court's opinion flatly proscribes recovery by Adkins of "all royalties accruing after Adkins' 1960 patent issued if Lear can prove patent invalidity." Ante, at 674. But recovery of pre-1960 royalties is left open by the Court, apparently because pre-issuance and post-issuance royalties do not stand on the same footing under federal law. Such a distinction may be valid, and pre-1960 royalties recoverable; but if so, what of post-1960 royalties which are attributable to the headstart Lear obtained over the rest of the industry as a result of pre-issuance disclosure of Adkins' idea? Today's bar to collection of post-1960 royalties would seem to be inflexible, and yet those royalties arguably are recoverable to the extent they represent payment for the pre-1960 disclosure of Adkins' idea; to that extent, they seem indistinguishable from pre-1960 royalties, at least for purposes of federal patent law. Cf. Brulotte v. Thys Co., 379 U.S. 29, 31 (1964). See also id., at 34-39 (dissenting opinion). This possibility and others serve to indicate the wisdom of refraining from any pronouncement now, and particularly from any rigid line drawing, in advance of consideration by the courts below and by the parties.
