Mr. Chief Justice Burger
delivered the opinion of the Court.
We granted certiorari to resolve a question on which there is a conflict in the courts of appeals: whether state trade Secret protection is pre-empted by operation of the federal patent law. In the instant case the Court of Appeals for the Sixth Circuit held that there was preemption. . The Courts of Appeals for the Second, Fourth, Fifth, and ..Ninth Circuits have reached the opposite conclusion.

Harshaw Chemical Co., an unincorporated division of petitioner, is a leading manufacturer of a type of synthetic crystal which is useful in the detection of ionizing radiation. In 1949 Harshaw commenced research into the growth of this type crystal and was able to produce one less than two inches in diameter. By 1966, as the result of expenditures in excess of $1 million, Harshaw was able to grow a 17-inch crystal, something no one else had done previously. Harshaw hád developed many processes, procedures, and manufacturing techniques in the purification of raw materials and the growth and encapsulation of the crystals which enabled it to accomplish this feat. Some of these processes Harshaw considers to be trade secrets.
The individual respondents ape former employees of Harshaw who formed or later joined respondent Bicron. While at Harshaw the individual respondents executed, as a condition of employment, at least one agreement each, requiring them not to disclose confidential information or trade secrets obtained as employees of Harshaw. Bicron was formed in August 1969 to compete with Harshaw in the production of the crystals; and by April 1970, had grown a 17-inch crystal.
Petitioner brought this diversity action in United States District Court for the Northern District of Ohio seeking injunctive relief and damages for the misappropriation of trade secrets. The District Court, applying Ohio trade secret law, granted a permanent injunction against the disclosure or use by respondents of 20 of the 40 claimed trade secrets until such time as the trade secrets had been released to the public, had otherwise generally become available to the public, or had been obtained by respondents from sources having the legal right to convey the information.
The Court of Appeals for the Sixth Circuit held that the findings of fact by the District Court were not clearly erroneous, and that it was evident from the record that the individual respondents appropriated to the benefit of Bicron secret information on processes obtained while they were employees at Harshaw. Further, the Court of Appeals held that the District Court properly applied Ohio law relating to trade secrets. Nevertheless, the Court of Appeals reversed the District Court, finding Ohio’s trade secret law to be in conflict with the patent •laws of the United States. The Court of Appeals reasoned that Ohio could not grant monopoly protection to processes and manufacturing techniques that were appropriate subjects for consideration under 35 U. S. C. § 101 for a federal patent but which had been in commercial use for over one year and so were no longer eligible for patent protection under 35 U. S. C. § 102 (b).
We hold that Ohio’s law of trade secrets is not preempted by the patent laws of the United States, and, accordingly, we reverse.
n
Ohio has adopted the widely relied-upon definition of a trade secret found at Restatement of Torts § 757, comment b (1939). B. F. Goodrich Co. v. Wohlgemuth, 117 Ohio App. 493, 498, 192 N. E. 2d 99, 104 (1963); W. R. Grace & Co. v. Hargadine, 392 F. 2d 9, 14 (CA6 1968). According to the Restatement,
“ [a] trade secret may consist of any formula, pattern, device or compilation of information which is used in one’s business, and which gives him an opportunity to obtain an advantage over competitors who do not know or use it. ft may be a formula for a chemical compound, a process of manufacturing, treating or preserving materials, a pattern for a- machine or other device, or a list of customers.”
The subject of a trade secret must be secret, and must not be of public knowledge or of a general knowledge in the trade or business. B. F. Goodrich Co. v. Wohlgemuth, supra, at 499, 192 N. E. 2d, at 104; National Tube Co. v. Eastern Tube Co., 3 Ohio C. C. R. (n. s.) 459, 462 (1902), aff’d, 69 Ohio St. 560, 70 N. E. 1127 (1903). This necessary element of secrecy is not lost, however, if the holder of the trade secret reveals the trade secret to another “in confidence, and under an implied obligation not .to use or disclose it.” Cincinnati Bell Foundry Co. v. Dodds, 10 Ohio Dec. Reprint 154, 156, 19 Weekly L. Bull. 84 (Super. Ct. 1887). These others may include those of the holder’s “employees to whom it is necessary to confide it, in order to apply it to the uses for which it is intended.” National Tube Co. v. Eastern Tube Co., supra, at 462. Often the recipient of confidential knowledge of the subject of a trade secret is a licensee of its holder. See Lear, Inc. v. Adkins, 395 U. S. 653 (1969).
The protection accorded the trade secret holder is against the .disclosure or unauthorized use of the trade secret by those to whom' the secret has been confided under the express or implied restriction of nondisclosure or nonuse. The law also protects the holder of a trade secret against disclosure or use .when the knowledge is gained, not by the owner’s volition, but by some “improper means,” Restatement of Torts § 757 (a),, which may include theft, wiretapping, or even aerial reconnaissance. A trade secret law, however, does not offer protection against discovery by fair and honest means, such as by independent invention, accidental disclosure, or by' so-called reverse engineering, that is by starting with the known product and working backward to divine the process' which .aided in its development or manufacture.
Novelty, in the patent law sense, is not required for a trade secret, W. R. Grace & Co. v. Hargadine, 392 F. 2d, at 14. “Quite clearly discovery is something less than invention.” A. O. Smith Corp. v. Petroleum Iron Works Co., 73 F. 2d 531, 538 (CA6 1934), modified to increase scope of injunction, 74 F. 2d 934 (1935). However, some novelty will be required if merely because that which does not possess novelty is usually known; secrecy, in the context of trade' secrets, thus implies at least minimal novelty.
The subject matter of a patent is limited to a “process, machine, manufacture, or composition of matter,, or ... . improvement thereof,” 35 U. "S. C. § 101, which fulfills the three conditions of novelty and utility as articulated and defined in 35 U. S. C. §§ 101 and 102, and nonobviousness, as set out in 35 U. S. C. § 103. If an invention xueets the rigorous statutory tests for the issuance of a patent, the patent is granted, for a period of 17 years, giving what has been described as the “right of exclusion,” R. Ellis, Patent Assignments and Licenses § 4, p. 7 (2d ed. 1943). This protection goes not only to copying the subject matter, which is forbidden under the Copyright Act, 17 U. S, C. § 1 et seq., but also to independent creation.

The first issue we deal with is whether the States are forbidden to act at all in the area of protection of the kinds of intellectual property which may make up the subject matter of trade secrets.
' Article I, § 8, cl. 8, of the Constitution grants to the Congress the power ■
“[t]o promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries . . . .”
In the 1972 Term, in Goldstein v. California, 412 U. S. 546 (1973), we held that the cl. 8 grant of power to Congress was not exclusive and that, at least in the case of writings, the States were not prohibited from encouraging and protecting the efforts of those within their borders by appropriate legislation. The States could, therefore, protect against the unauthorized rerecording for sa,le of performances fixed on records or tapes, even though those performances qualified as “writings” in the constitutional sense and Congress was empowered to legislate regarding such performances and could pre-empt the area if it chose to do so. This determination was premised on the great diversity of interests in .our Nation — the essentially nonuniform character of the. appreciation of intellectual achievements in the various States. Evidence for this came from patents granted by the States in the 18th century. 412 U. S., at 557.
Just as the States may exercise regulatory power over writings so may the States regulate with respect to discoveries. States may hold diverse viewpoints in protecting intellectual property relating to invention as they do in protecting the intellectual property relating to the subject matter of copyright. The only limitation on the States is that in regulating the area of patents and copyrights they do not conflict with the operation of the laws in this area passed by Congress, and it is to that more difficult question, we now turn.
IV
The .-question of whether the trade secret law of Ohio is void under the Supremacy Clause involves a consideration of whether that law “stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress.” Hines v. Davidowitz, 312 U. S. 52, 67 (1941). See Florida Avocado Growers v. Paul, 373 U. S. 132, 141 (1963). We stated in Sears, Roebuck &. Co. v. Stiffel Co., 376 U. S. 225, 229 (1964), that when state law touches upon'the area of federal statutes enacted pursuant to constitutional authority, “it is-'familiar doctrine’ that the federal policy ‘may not be set at naught, or its benefits denied’ by the state law. Sola Elec. Co. v. Jefferson Elec. Co., 317 U. S. 173, 176 (1942). This is true, of course, even, if the state law is enacted in the exercise of otherwise undoubted state power.”
The laws which the .Court of Appeals in this case held to be in conflict, with the Ohio law.of.trade secrets were the patent laws passed by the Congress in the unchallenged, exercise'of its clear power under Art. I, §8, cl. 8, of the Constitution. The patent law does not explicitly endorse or forbid the operation of trade secret law. However, as we have noted, if the scheme of protection developed by Ohio respecting trade secrets “clashes with the objectives of the federal patent laws,” Sears, Roebuck & Co. v. Stiffel Co., supra, at 231, then the state law must-fall. To determine whether the Ohio' law “clashes” with the federal law it is helpful to examine the objectives of both the patent and trade secret, laws».
. The stated objective of the Constitution in granting the power to Congress to legislate in the area of intellectual property is. to, “promote the Progress of Science and. useful Arts.”. The patent laws promote this progress by offering a right of 'exclusion for a limited period as an incentive* to inventors to risk the often enormous costs in'-terms of time, research, and development. .The productive effort thereby fostered will have a positive effect on societyithrough the introduction of new products, and processes of manufacture into (the economy, and the emanations by why of increased employment and better lives for our citizens. In return, for the right of ex'clusion — this “reward for inventions,” Universal Oil Co. v. Globe Co., 322 U. S. 471, 484 (1944) — the patent laws impose upon the inventor a requirement of disclosure. To insure adequate and full disclosure so that upon the expiration of the 17-year period “the . knowledge of the invention enures to the people, who are thus enabled without restriction to practice it and profit by its use,” United States v. Dubilier Condenser Corp., 289 U. S. 178, 187 (1933), the patent laws require' that the patent application shall include a full and clear description of the invention and “of the manner and process of making and using it” so that any person skilled in the art may make and use the invention. 35 U. S. C. § 112. When a patent is granted and the information contained in it is circulated to the general public and those especially skilled in the trade, such additions to the general store óf knowledge are of such importance to the public weal that the Federal Government is willing to pay the high price of 17 years of exclusive use for its disclosure, which' disclosure, it is assumed, will stimulate ideas and the eventual development.of further significant advances in the art. The Court has also articulated another policy of the patent law: that which is in the public domain cannot be removed therefrom by action of the States.
“[FJederal law requires that all ideas in general circulation be dedicated to the common good unless they are protected by a valid patent.” Lear, Inc. v. Adkins, 395 U. S., at 668.
See also Goldstein v. California, 412 U. S., at 570-571; Sears, Roebuck & Co. v. Stiffel Co., supra; Compco Corp. v. Day-Brite Lighting, Inc., 376 U. S. 234, 237-238 (1964); International News Service v. Associated Press. 248 U. S. 215, 250 (1918) (Brandéis, J., dissenting).
The maintenance of standards of commercial ethics and the encouragement of invention are the broadly stated policies behind trade secret law. “The necessity of good faith and honest, fair dealing, is the very life and spirit of the commercial world.” National Tube Co. v. Eastern Tube Co., 3 Ohio C. C. R. (n. s.), at. 462. In A. O. Smith Corp. v. Petroleum Iron Works Co., 73 F. 2d, at 539, the Court emphasized that even though a discovery may not be patentable, that does not
“destroy the value of the discovery to one who makes it, or advantage the competitor who by unfair means, or as the beneficiary of a broken faith, obtains thé desired knowledge without himself paying the price in lábor, money, or machines expended by the discoverer.”
In Wexler v. Greenberg, 399 Pa. 569, 578-579, 160 A. 2d 430, 434-435 (1960), the Pennsylvania Supreme Court noted the importance, of trade secret protection to the subsidization of. research and- development and to increased economic efficiency within large companies through the dispersion of responsibilities for creative developments.
Having now in mind the objectives of both the patent and trade secret law, we turn to an examination of the interaction of these systems of protection of intellectual property-one established by the Congress' and the other by a State — to determine whether , and under7 what circumstances the latter might constitute “too great an encroachment on the federal patept system to be tolerated.” Sears, Roebuck & Co. v. Stiffel Co., 376 U. S., at 232.
As ,we noted earlier,, trade secret law protects items which would not be proper subjects for consideration for patent protection under 35 U. S. C. §101. As dn the' case of the recordings in Goldstein v. California, Congress, with respect to nonpatentable subject matter, “has drawn no balance; rather, it has left the area unattended, and no reason exists why the State should not be free to act.” Goldstein v. California, supra, at 570 (footnote omitted).
Since no patent is available for a discovery, however useful, novel, and nonobvious, unless it falls within one of the express categories of patentable subject matter of 35 U. S. C. § 101, the holder of such a discovery would have no reason to apply for a patent whether trade secret' protection existed or not. Abolition of trade secret protection would, therefore, not result in increased disclosure to the public of discoveries in the area of nonpatentable subject matter. Also, it is hard to see how the public would be benefited by disclosure of customer lists or advertising campaigns; in fact, keeping such items secret encourages businesses to initiate new and individualized plans of operation, and constructive competition results. This, in turn, leads to a greater variety of business methods than would otherwise be the case if privately developed marketing and other data were passed illicitly among firms involved in the same enterprise.
Congress has spoken in the area of those discoveries which fall within one of the categories of patentable subject matter of 35 U. S. C. § 101 and which are, therefore, of a nature that would be subject to consideration for a patent. Processes, machines, manufactures, compositions of matter, and improvements thereof, which meet the tests of utility, novelty, and nonobviousness are entitled to be patented, but those which do not, are not. The question remains whether those items which are proper subjects for consideration for a patent may also have available the alternative, protection accorded by trade secret law.
Certainly the patent policy of encouraging invention is not disturbed by the existence of another form of incentive to invention. In this respect the two; systems are not and never would be in conflict. Similarly, the policy that matter once in- the public domain must remain in the- public domain is not incompatible with the existence of trade secret protection. By definition a trade secret has not been placed in the public domain.
The more difficult objective of the patent law to reconcile with trade secret law is that of disclosure, the quid pro quo of the right to exclude. Universal Oil Co. v. Globe Co., 322 U. S., at 484. We' are helped in this stage of the analysis by Judge Henry Friendly’s opinion in Painton & Co. v. Bourns, Inc., 442 F. 2d 216 (CA2 1971). There the Court of Appeals thought it useful, in determining whether inventors will refrain because of the existence of trade secret law from applying for patents, thereby depriving the public from learning of the invention, to distinguish between three categories of trade secrets: '
“(1) the trade secret believed by its owner to constitute a validly patentable invention; (2) the trade secret known to its owner not to be so patentable; and (3) the trade secret whose valid patentability is considered5 dubious.” . Id., at 224.
Trade .secret protection in each of these categories would run against breaches of confidence — the employee and licensee situations — and theft and other forms of industrial espionage.
As to. the trade secret known not to meet "the standards of patentability, very little in the way of disclosure would be accomplished by abolishing trade secret' protection. With trade secrets of nonpatentable subject matter, the patent alternative would not reasonably be available to the inventor. “There can be no public interest in stimulating- developers of such [unpatentable] know-how to flood an overburdened Patent Office with applications [for] what they do npt consider patentable.” Ibid. The- mere filing of applications doomed to be turned down by the Patent Office will bring forth no new public knowledge or enlightenment, since under federal statute and regulation patent applications and abandoned patent applications are held by the Patent Office in confidence and are not open to public inspection. 35 U. S. C. § 122; 37 CFR § 1.14 (b). .
Even as the extension of trade secret protection to patentable subject matter that the owner knows will not meet the standards of patentability will not conflict with the patent policy of disclosure, it will Rave a decidedly beneficial effect on society. Trade secret law will encourage invention in areas where patent law does not reach, and will prompt the independent innovator to proceed with the discovery and exploitation of his invention. Competition is fostered and the public is not deprived of the use of valuable, if not quite patentable, invention.
Even if trade secret protection against the faithless employee were abolished, inventive and exploitive effort in the .area of patentable subject matter that did iiot meet the standards of patentability would continue, although at a reduced level. Alternatively with the effort that remained, however, would come an increase in the amount of self-help that innovative companies would employ. Knowledge would be widely dispersed among the employees of those still active in research. Security precautions necessarily would be increased, and salaries and fringe benefits of those few officers or employees who had to know the whole of the secret invention would be fixed in an amount thought sufficient to assure their loyalty. Smaller companies would be placed at a distinct economic disadvantage, since the costs of this kind of self-help could be great, and the cost to the public of the use of this invention would be increased. The innovative entrepreneur with limited resources would tend to confine his r ¡Search efforts to himself and those few he felt he could > mst without the ultimate assurance of legal protection against breaches of confidence. As a result, organized scientific and technological research could become fragmented, and society, as a whole, would suffer.
Another problem that would arise if state trade secret protection were precluded is in the area of licensing others to exploit secret processes. The holder óf a trade secret would not likely share his secret with a manufacturer who cannot be placed under binding legal obligation to pay a license fee or to protect the secret. The result would be to hoard rather than disseminate knowledge. Painton & Co. v. Bourns, Inc., 442 F. 2d, at 223. Instead, then,- of licensing others to use his invention and making the most efficient use of existing manufacturing and marketing structures within the industry, the trade secret holder would tend either to limit his utilization of the invention, thereby depriving the public of the maximum benefit of its use, or engage in the time-consuming and economically wasteful enterprise of constructing duplicative manufacturing and marketing mechanisms for the exploitation of the invention. The detrimental misallbcation of resources and economic waste that would thus take place if trade secret protection were abolished with respect to employees or licensees cannot be justified by reference to any policy that the federal patent law seeks to advance.
Nothing in the patent law. requires that States refrain from action to prevent industrial espionage. In addition to the increased costs for protection from burglary, wiretapping, bribery, and the other means used to misappropriate trade secrets, there is the inevitable cost to the basic decency of society when one firm steals from another. A most fundamental human right, that of privacy, is threatened when industrial espionage is con-, doned or is made profitable^ the state interest in denying profit to such illegal ventures is unchallengeable.
The next category of patentable subject matter to deal with is theG invention Whose holder has a legitimate doubt as to its patentability. The risk of eventual patent invalidity by the courts -and the costs associated with that risk may well impel some with a good-faith doubt as to patentability not to take the trouble to seek to obtain and defend patent protection for their discoveries, regardless of the existence of trade secret protection. Trade secret protection would assist those inventors in the more efficient exploitation óf their discoveries and not conflict with the patent l$w. In most cases of genuine doubt as'to patent validity the potential rewards of patent protection are so far superior to those accruing to holders of trade secrets, that the holders of such inventions will seek patent protection, ignoring the trade secret route. For those inventors “on the line” as to whether to seek patent protection, the abolition of trade secret protection might encourage some to. apply for a patent who otherwise would not have done so. For some of those so encouraged, no patent will be granted and the result
“will have been an unnecessary postponement in the divulging of the trade secret to persons, willing to pay for it. If [the patent does issue], it may well be invalid, yet many will prefer to pay a modest royalty than to contest it, even though Lear allows them to accept a license and pursue the contest without paying royalties while the.fight goes on. The. result in such a case would be unjustified royalty payments from many who would prefer not to pay them rather than agreed fees from one or a few who are entirely willing to do so.” Painton & Co. v. Bourns, Inc., 442 F. 2d, at 225.
The point is that those who might be encouraged to file for patents by the absence of trade secret law will include inventors possessing the chaff as well as the wheat.' Some of the chaff — the nonpatentablfe discoveries — will be thrown out by the Patent Office, but in the meantime society will have been deprived of use of those discoveries through trade secret-protected licensing. Some of the. chaff may not be thrown out. This Court has noted the difference between the standards used by the Patent Office and the courts to determine patentability. Graham v. John Deere Co., 383 U. S. 1, 18 (1966). In Lear, Inc. v. Adkins, 395 U. S. 653 (1969), the Court thought that an invalid patent was so serious a threat to the free use of ideas already in the public domain that the Court permitted licensees of the patent holder to challenge, the validity of the patent. Better had the invalid patent, never been issued. More of those patents would likely issue if trade secret law were abolished. Eliminating trade secret law for the doubtfully patentable invention is thus likely to have deleterious effects on society and patent policy which we cannot say are balanced out by the speculative gain which might result from the encouragement of some inventors with doubtfully patentable inventions which -deserve patent protection to come forward and apply for patents. • There is no conflict, then, between trade'secret, law and the patent law policy of disclosure, at least insofar as the first two categories of patentable subject matter are concerned.
The final category of patentable subject matter to deal with is the clearly patentable invention, i. e., that invention which the owner believes to meet the standards of patentability. It is here that the federal interest in disclosure is at its peak;- these inventions, novel, useful and non obvious, are “ ‘the things which, are worth to the public .the embarrassment of an exclusive patent.’ ” Graham v. John Deere Co., supra, at 9 (quoting. Thomas Jefferson). The interest of the public is that the bargain of 17 years of exclusive use in return for disclosure be accepted. If a State, through a system of protection, were to cause a substantial risk that holders of patentable inventions would not seek .patents, but rather would -rely on the state protection, we would be compelled to hold that such a system could not constitutionally cbntinue to exist. In the case of trade secret law no reasonable risk of déterrence from patent application by' those who can reasonably expect' to be granted patents exists.
■ Trade Secret law provides far weaker protection in many'.respects than the patent law. While trade secret law does not forbid the discovery of the trade secret by fair and honest means, e. g., independent creation or reverse- engineering, patent law operates “against the world,” forbidding any use of the invention -for whatever purpose for a significant length of time. The holder of a trade secret also takes a substantial risk that the secret will be passed on to his competitors, by theft or by breach of a confidential relationship, in a manner not easily susceptible of discovery or proof. Painton & Co. v. Bourns, Inc., 442 F. 2d, at 224. Where patent law acts as a barrier, trade secret law functions relatively as a sieve. ' The possibility that an inventor who believes his invention meets the standards of patentability will sit back, rely on trade secret law, and after one year of use forfeit any right to patent protection, 35 U. S. C. § 102 (b), is rémote indeed.
Nor does society face much risk that scientific Or technological progress will be impeded by the rare inventor with a patentable invention who chooses trade secret protection over patent protection. The ripeness-of-time concept of invention, developed from the study of the -many independent multiple, discoveries in history, predicts. that if a particular individual had not made a particular discovery others would.have, and in probably a relatively short period of time. ' If something is to be discovered at all- very likely it will be discovered by more than one person. Singletons and Multiples in Science (1961), in R. Merton, The Sociology of Science 343 (1973); J. Cole & S. Cole, Social Stratification in Science 12-13, 229-230 (1973); Ogburn & Thomas, Are Inventions Inevitable?, 37 Pol. Sci. Q. 83 (1922). Even were an inventor to keep his discovery completely to himself, something that neither the patent nor trade secret laws forbid, there is a high probability that it will be soon independently developed. If the invention, though still a trade secret, is put into public use, the competition is alerted to the existence of the inventor’s solution to the problem and may be encouraged to make an extra effort to independently find the solution thus known to be possible. The inventor faces pressures not only from private industry, but from the skilled scientists who work in our universities and our other great publicly supported centers of learning and research.
We conclude that the extension of trade secret protection to clearly patentable inventions does not conflict with the patent policy of disclosure. Perhaps because trade secret law does not produce any positive effects in the. area of clearly patentable inventions, as opposed to the beneficial effects resulting from trade secret protection in the areas of the doubtfully patentable and the clearly unpatentable inventions, it has been suggested that partial pre-emption may be appropriate, and that courts should refuse to apply trade secret protection to inventions which the holder should have patented, and which would have been, thereby, disclosed. However, since' there is no real possibility that trade secret law will conflict with the federal policy favoring disclosure of clearly patentable inventions partial pre-emption is inapprbpriate. Partial pre-emption, furthermore, could well create serious problems for state courts in the administration of trade secret law. As a preliminary matter in trade secret actions, state courts would be obliged to distinguish between what a reasonable inventor would and would not <correctly consider to be clearly patentable, with the holder of the trade secret arguing that the invention was not patentable and the misappropriator of. the trade secret árguing its undoubted novelty, utility, and -non-obviousness. Federal courts have a difficult enough time trying to determine whether an invention, narrowed by the patent application procedure and fixed in the specifications which describe the invention for which the patent has been granted,, is patentable/ Although state courts in some circumstances must join federal courts in judging whether an issued patent is valid, Lear, Inc. v. Adkins, supra, it would be undesirable ■ to. impose the almost impossible burden on state courts to determine the patentability — in fact and in the mind of a' reasonable inventor — of a discovery which has not been patented and remains entirely uncircumscribed by expert analysis in the administrative process. . Neither complete nor partial pre-emption of state trade secret,law is justified.
Our conclusion that patent, law does not pre-empt trade secret law is in accord with prior cases of this Court. Universal Oil Co. v. Globe Co., 322 U. S., at 484; United States v. Dubilier Condenser Corp., 289 U. S., at 186—187; Becher v. Contoure Laboratories, 279 U. S. 388, 391 (1929); Du Pont Powder Co. v. Masland, 244 U. S. 100, 102 (1917); Dr. Miles Medical Co. v. Park & Sons Co., 220 U. S. 373, 402-403 (1911); Board of Trade v. Christie Grain & Stock Co., 198 U. S. 236, 250-251 (1905). Trade secret law and patent law have co-existed in this country for over one hundred years. Each has its particular, role to play, and the operation of one does not take away from the need for the other. Trade secret law encourages the development and exploitation of those items of lesser or different invention than might be ac- ‘ corded protection under the patent laws, but which items still have an important part to play in the technological •and scientific advancement of the Nation. Trade secret law promotes the sharing of knowledge, and the efficient operation of industry; it permits the individual inventor to reap the rewards of his labor by contracting with a company large'enough to develop and exploit it. Congress, by its silence over these many years, has seen the wisdom of allowing the States to enforce trade secret protection.. Until Congress takes affirmative action to the contrary, States should be free to grant protection to trade secrets.
Since we- hold that Ohio trade secret law is not preempted by the federal patent law, the judgment of the Court of Appeals for the Sixth Circuit is reversed,, and the case is remanded to the Court of Appeals with directions to reinstate the judgment of the District Court.
It 'is- so ordered.

“§ 101. Inventions patentable
“Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
“§ 102. Conditions for patentability; novelty and loss of right to patent .
“A person shall be entitled to a patent unless—
“(a) the invention was known or used by others in this country, or patented or 'described in a printed publication in this or a foreign country, before the invention thereof by the applicant for patent, or
“(b) the invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country, more than one year prior to the date' of the application for patent in the United States, or
“(c) he has abandoned the invention, or
“(d) the invention was first patented or caused to be patented, or was the subject of an inventor’s certificate, by the applicant or his legal representatives. or assigns in a foreign country prior to the date of the application for patent in this country on an application for patent or inventor’s certificate filed more than- twelve months before the filing of the application in the United States, or
“(e) the invention was described in a patent granted on an application for patent by another filed in the United States before the invention thereof by the applicant for patent, or
“(f) he did not himself invent the subject matter sought to be patented, or
“(g) before the applicant’s invention thereof the invention was made in this country by another who had not abandoned, suppressed, or concealed it. In determining priority of invention there shall be considered not only the respective dates of conception and reduction to practice of the invention, but also the reasonable diligence of one who was first to conceive and last to reduce to practice, from a time prior to conception by the other.
. “§ 103. Conditions for patentability; non-obvious-subjebt matter
“A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole .would have been obvious at the time the invention was made to a person- having ordinary skill in-the art to.which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made.”
Title 35 U. S. C. § 154 provides:
“Every patent shall contain a short title of the invention and a grant to the patentee,. his heirs or assigns, for the term of seventeen years, subject .to the payment of issue fees as provided for in ..this title, of the right to exclude others from making, using, or selling the invention throughout the United States, referring to the specification for the particulars thereof.

The Court of Appeals below relied, iñ part, on Kendall v. Winsor, 21 How. 322 (1859), a case decided nine years before trade secret law was imported into this country f-om England by means of the landmark case of Peabody v. Norfolk, 98 Mass. 452 (1868).
What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.
