Harshaw Chemical Co., an unincorporated division of petitioner,
over a period of years, developed certain processes in the growth
and encapsulation of synthetic crystals and purification of raw
materials, some of which processes were considered to be trade
secrets; it eventually succeeded for the first time in growing a
17-inch crystal of a type useful in the detection of ionizing
radiation. The individual respondents, former employees of Harshaw
who. while working there. had signed agreements not to disclose
trade secrets obtained as employees, formed or later joined
respondent Bicron Corp., which competed with Harshaw in producing
crystals; Bicron, soon after its formation, also grew a 17-inch
crystal. Petitioner brought this diversity action seeking
injunctive relief and damages for misappropriation of trade
secrets. The District Court, applying Ohio trade secret law,
granted a permanent injunction. The Court of Appeals reversed on
the ground that Ohio's trade secret law conflicted with the federal
patent laws.
Held: Ohio's trade secret law is not preempted by the
federal patent laws. Pp.
416 U. S.
474-493.
(a) The States are not forbidden to protect the kinds of
intellectual property that may make up the subject matter of trade
secrets; just as the States may exercise regulatory power over
writings,
Goldstein v. California, 412 U.
S. 546, so may they regulate with respect to
discoveries, the only limitation being that regulation in the area
of patents and copyrights must not conflict with the operation of
federal laws in this area. Pp.
416 U. S.
478-479.
(b) Abolition of trade secret protection would not result in
increased disclosure to the public of discoveries in the area of
nonpatentable subject matter, and the public would not be benefited
by disclosure of such discoveries. Pp.
416 U. S. 482
483.
(c) The federal patent policy of encouraging invention is not
disturbed by the existence of another form of incentive to
invention such as trade secret protection, and, in this respect,
the two systems are not in conflict. P.
416 U. S.
484.
(d) Nor is the patent policy that matter once in the public
domain must remain there incompatible with the existence of trade
secret protection. P.
416 U. S.
484.
Page 416 U. S. 471
(e) Nor is there any conflict between trade secret law and the
patent policy of disclosure whether a trade secret concerning
patentable subject matter is in the category of discovery which is
(1) clearly unpatentable, (2) doubtfully patentable, or (3) clearly
patentable. As to the first category, the patent alternative is not
available, and trade secret law will encourage invention and prompt
the innovator to proceed with the discovery and exploitation of his
invention, and to license others to exploit secret processes. As to
the second category, the risk and cost of eventual patent
invalidity may impel the inventor not to seek patent protection
regardless of the existence of trade secret law, and the
encouragement by the elimination of trade secret protection of
patent applications by some with doubtfully patentable inventions
is likely to have a deleterious effect on society and patent
policy. As to the third category, trade secret law, which affords
weaker protection than the patent laws, presents no reasonable risk
of deterrence from patent application. Pp.
416 U. S.
484-491.
(f) There being no real possibility that trade secret law will
conflict with federal patent policy, partial preemption as to
clearly patentable inventions would not be appropriate, and could
well unnecessarily burden administration of trade secret law by
States. Pp.
416 U. S.
491-492.

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 preempted by operation of the federal patent law.
[
Footnote 1] In the instant
case, the Court of Appeals for the Sixth Circuit held that there
was preemption. [
Footnote 2]
The Courts of Appeals for the Second, Fourth, Fifth, and Ninth
Circuits have reached the opposite conclusion. [

I
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 had 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 are 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
Page 416 U. S. 474
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.
II
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.
Naradine, 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
Page 416 U. S. 475
know or use it. It 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. [
Footnote 4] The law also protects the holder of a
trade
Page 416 U. S. 476
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. [
Footnote 5] 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. [
Footnote 6]
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. [
Footnote 7]
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,
Page 416 U. S. 477
as set out in 35 U.S.C. § 103. [
Footnote 8] If an invention meets the rigorous statutory
tests for the issuance of a patent, the patent is granted, for a
period of 17
Page 416 U. S. 478
years, giving what has been described as the "right of
exclusion," R. Ellis, Patent Assignments and Licenses § 4, p. 7 (2d
ed.1943). [
Footnote 9] 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.
III
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
Page 416 U. S. 479
appropriate legislation. The States could, therefore, protect
against the unauthorized rerecording for sale 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 preempt 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
412 U. S.
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,
312 U. S. 67
(1941).
See Florida Avocado Growers v. Paul, 373 U.
S. 132,
373 U. S. 141
(1963). We stated in
Sear, Roebuck Co. v. Stiffel Co.,
376 U. S. 225,
376 U. S. 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
Page 416 U. S. 480
'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,
317 U. S. 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
376 U. S. 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
society through the introduction of new products and processes of
manufacture into the economy, and the emanations by way of
increased employment and better lives for our citizens. In return
for the right of exclusion -- this "reward for inventions,"
Universal Oil Co. v. Globe Co., 322 U.
S. 471,
322 U. S. 484
(1944) -- the patent laws impose upon the inventor a requirement of
disclosure. To insure adequate and full disclosure so that upon
the
Page 416 U. S. 481
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,
289 U. S. 187
(1933), the patent laws require [
Footnote 10] 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 of 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. "[F]ederal 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
395 U. S. 668.
See also Goldstein v. California, 412 U.S. at
412 U. S.
570-571;
Sears, Roebuck & Co. v. Stiffel Co.,
supra; Compco Corp. v. Day-Brite Lighting, Inc., 376 U.
S. 234,
376 U. S.
237-238 (1964);
International News Service v.
Associated Press, 248 U. S. 215,
248 U. S. 250
(1918) (Brandeis, 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
Page 416 U. S. 482
and spirit of the commercial world."
National Tube Co. v.
Eastern Tube Co., 3 Ohio C.C.R. (n.s.), at 462. [
Footnote 11] 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 a the beneficiary
of a broken faith, obtains the desired knowledge without himself
paying the price in labor, 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. [
Footnote 12]
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
under what circumstances the latter might constitute "too great an
encroachment on the federal patent system to be tolerated."
Sears, Roebuck & Co. v. Stiffel Co., 376 U.S. at
376 U. S.
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 in the
Page 416 U. S. 483
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
412 U. S. 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.
Page 416 U. S. 484
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. [
Footnote 13]
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
322 U. S. 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 considered 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
Page 416 U. S. 485
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 not 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 have 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. [
Footnote 14]
Even if trade secret protection against the faithless employee
were abolished, inventive and exploitive effort in the area of
patentable subject matter that did not 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
Page 416 U. S. 486
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. [
Footnote
15] 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 research efforts to himself and
those few he felt he could trust 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 of 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
Page 416 U. S. 487
constructing duplicative manufacturing and marketing mechanisms
for the exploitation of the invention. The detrimental
misallocation 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 condoned or is
made profitable; [
Footnote
16] the state interest in denying profit to such illegal
ventures is unchallengeable.
The next category of patentable subject matter to deal with is
the 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 of their discoveries and not conflict with
the patent law. 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
Page 416 U. S. 488
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 nonpatentable
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,
383 U. S. 18
(1966). [
Footnote 17] 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
Page 416 U. S. 489
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 nonobvious, are "
the things
which are worth to the public the embarrassment of an exclusive
patent.'" Graham v. John Deere Co., supra, at 383 U. S. 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 continue to exist. In the case of trade secret
law, no reasonable risk of deterrence from patent application by
those who can reasonably expect to be granted patents
exists.
Trade secret law provides far weaker protection in
Page 416 U. S. 490
many respects than the patent law. [
Footnote 18] 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 remote 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).
[
Footnote 19] Even
Page 416 U. S. 491
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 preemption 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. [
Footnote 20]
However, since there is no real possibility that trade secret law
will conflict with the federal policy favoring disclosure of
clearly patentable inventions, partial preemption is
inappropriate.
Page 416 U. S. 492
Partial preemption, 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 arguing
its undoubted novelty, utility, and nonobviousness. Federal courts
have a difficult enough time trying to determine whether an
invention, narrowed by the patent application procedure [
Footnote 21] and fixed in the
specifications which describe the invention for which the patent
has been granted, is patentable. [
Footnote 22] 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 preemption of
state trade secret law is justified. Our conclusion that patent law
does not preempt trade secret law is in accord with prior cases of
this Court.

Footnote 23] Trade secret law and patent law have
coexisted 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 accorded 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.

The Court of Appeals below relied, in part, on
Kendall v.
Winsor, 21 How. 322 (1859), a case decided nine
years before trade secret law was imported into this country from
England by means of the landmark case of
Peabody v.
Norfolk, 98 Mass. 452 (1868).
MR. JUSTICE MARSHALL, concurring in the result.
Unlike the Court, I do not believe that the possibility that an
inventor with a patentable invention will rely
Page 416 U. S. 494
on state trade secret law, rather than apply for a patent is
"remote indeed."
Ante at
416 U. S. 490.
State trade secret law provides substantial protection to the
inventor who intends to use or sell the invention himself, rather
than license it to others, protection which, in its unlimited
duration, is clearly superior to the 17-year monopoly afforded by
the patent laws. I have no doubt that the existence of trade secret
protection provides, in some instances, a substantial disincentive
to entrance into the patent system, and thus deprives society of
the benefits of public disclosure of the invention which it is the
policy of the patent laws to encourage. This case may well be such
an instance.
But my view of sound policy in this area does not dispose of
this case. Rather, the question presented in this case is whether
Congress, in enacting the patent laws, intended merely to offer
inventors a limited monopoly in exchange for disclosure of their
invention, or instead to exert pressure on inventors to enter into
this exchange by withdrawing any alternative possibility of legal
protection for their inventions. I am persuaded that the former is
the case. State trade secret laws and the federal patent laws have
co-existed for many, many years. During this time, Congress has
repeatedly demonstrated its full awareness of the existence of the
trade secret system, without any indication of disapproval. Indeed,
Congress has, in a number of instances, given explicit federal
protection to trade secret information provided to federal
agencies.
See, e.g., 5 U.S.C. § 552(b)(4); 18 U.S.C. §
1905;
see generally Appendix to Brief for Petitioner.
Because of this, I conclude that there is
"neither such actual conflict between the two schemes of
regulation that both cannot stand in the same area, nor evidence of
a congressional design to preempt the field."

MR. JUSTICE DOUGLAS, with whom MR. JUSTICE BRENNAN concurs,
dissenting.
Today's decision is at war with the philosophy of
Sears,
Roebuck & Co. v. Stiffel Co., 376 U.
S. 225, and
Compco Corp. v. Day-Brite Lighting,
Inc., 376 U. S. 234.
Those cases involved patents -- one of a pole lamp and one of
fluorescent lighting fixtures -- each of which was declared
invalid. The lower courts held, however, that though the patents
were invalid, the sale of identical or confusingly similar products
to the products of the patentees violated state unfair competition
laws. We held that, when an article is unprotected by a patent,
state law may not forbid others to copy it, because every article
not covered by a valid patent is in the public domain. Congress, in
the patent laws, decided that, where no patent existed, free
competition should prevail; that, where a patent is rightfully
issued, the right to exclude others should obtain for no longer
than 17 years, and that the States may not,
"under some other law, such as that forbidding unfair
competition, give protection of a kind that clashes with the
objectives of the federal patent laws, [
Footnote 2/1]"
376 U.S. at
376 U. S.
231.
The product involved in this suit, sodium iodide synthetic
crystals, was a product that could be patented, but was not.
Harshaw, the inventor, apparently contributed greatly to the
technology in that field by developing processes, procedures, and
techniques that produced
Page 416 U. S. 496
much larger crystals than any competitor. These processes,
procedures, and techniques were also patentable, but no patent was
sought. Rather, Harshaw sought to protect its trade secrets by
contracts with its employees. And the District Court found that, as
a result of those secrecy precautions, "not sufficient disclosure
occurred so as to place the claimed trade secrets in the public
domain," and those findings were sustained by the Court of
Appeals.
The District Court issued a permanent injunction against
respondents, ex-employees, restraining them from using the
processes used by Harshaw. By a patent, which would require full
disclosure, Harshaw could have obtained a 17-year monopoly against
the world. By the District Court's injunction, which the Court
approves and reinstates, Harshaw gets a permanent injunction
running into perpetuity against respondents. In
Sears, as
in the present case, an injunction against the unfair competitor
issued. We said:
"To allow a State by use of its law of unfair competition to
prevent the copying of an article which represents too slight an
advance to be patented would be to permit the State to block off
from the public something which federal law has said belongs to the
public. The result would be that, while federal law grants only 14
or 17 years' protection to genuine inventions,
see 35
U.S.C. §§ 154, 173, States could allow perpetual protection to
articles too lacking in novelty to merit any patent at all under
federal constitutional standards. This would be too great an
encroachment on the federal patent system to be tolerated."
376 U.S. at
376 U. S.
231-232.
The conflict with the patent laws is obvious. The decision of
Congress to adopt a patent system was based on the idea that there
will be much more innovation if discoveries are disclosed and
patented than there will be when everyone works in secret. Society
thus fosters a
Page 416 U. S. 497
free exchange of technological information at the cost of a
limited 17-year monopoly. [
Footnote
2/2]
A trade secret, [
Footnote 2/3]
unlike a patent, has no property dimension. That was the view of
the Court of Appeals, 478 F.2d 1074, 1081, and its decision is
supported by what Mr. Justice Holmes said in
Du Pont Powder Co.
v. Masland, 244 U. S. 100,
244 U. S.
102:
"The word property, as applied to trade-marks and trade secrets,
is an unanalyzed expression of certain
Page 416 U. S. 498
secondary consequences of the primary fact that the law makes
some rudimentary requirements of good faith. Whether the plaintiffs
have any valuable secret or not the defendant knows the facts,
whatever they are, through a special confidence that he accepted.
The property may be denied, but the confidence cannot be.
Therefore, the starting point for the present matter is not
property or due process of law, but that the defendant stood in
confidential relations with the plaintiffs, or one of them. These
have given place to hostility, and the first thing to be made sure
of is that the defendant shall not fraudulently abuse the trust
reposed in him. It is the usual incident of confidential relations.
If there is any disadvantage in the fact that he knew the
plaintiffs' secrets, he must take the burden with the good.
[
Footnote 2/4]"
A suit to redress theft of a trade secret is grounded in tort
damages for breach of a contract -- a historic remedy,
Cataphote Corp. v. Hudson, 422 F.2d 1290. Damages for
breach of a confidential relation are not preempted by this patent
law, but an injunction
Page 416 U. S. 499
against use is preempted because the patent law states the only
monopoly over trade secrets that is enforceable by specific
performance, and that monopoly exacts as a price full disclosure. A
trade secret can be protected only by being kept secret. Damages
for breach of a contract are one thing; an injunction barring
disclosure does service for the protection accorded valid patents,
and is therefore preempted.
From the findings of fact of the lower courts, the process
involved in this litigation was unique, such a great discovery as
to make its patentability a virtual certainty. Yet the Court's
opinion reflects a vigorous activist anti-patent philosophy. My
objection is not because it is activist. This is a problem that
involves no neutral principle. The Constitution in Art. I, § 8, cl.
8, expresses the activist policy which Congress has enforced by
statutes. It is that constitutional policy which we should enforce,
not our individual notions of the public good.
I would affirm the judgment below.
[
Footnote 2/1]
Here, as in
Lear, Inc. v. Adkins, 395 U.
S. 653,
395 U. S. 674,
which held that a licensee of a patent is not precluded by a
contract from challenging the patent, for if he were, that would
defeat the policy of the patent laws: "enforcing this contractual
provision would undermine the strong federal policy favoring the
full and free use of ideas in the public domain."
[
Footnote 2/2]
"The holding [of the Court of Appeals] in
Kewanee seems
correct. If it is permissible for an inventor to use the law of
unfair competition as a substitute for patenting, certain
categories of inventions would receive privileged protection under
that law. Thus, a new laser, television set, or airplane could not
be protected because inventions which by their nature cannot be put
into commercial use without disclosure, are not eligible for trade
secret protection after they are put on the market. Those that can
be maintained are eligible. But as the basic economic function of
the patent system is to encourage the making and commercialization
of inventions, there seems to be no justification for providing
incentives beyond those provided by the patent law to discriminate
between different categories of inventions,
i.e., those
that may inherently be kept secret and those that may not.
Moreover, state rules which would grant such incentives seem to
conflict with the economic
quid pro quo underlying patent
protection;
i.e., a monopoly limited in time, in return
for full disclosure of the invention. Thus, federal law has struck
a balance between incentives for inventors and the public's right
to a competitive economy. In this sense, the patent law is an
integral part of federal competitive policy."

Conflict, 1 APLA Quarterly Journal 296, 298-299 (1973).
[
Footnote 2/3]
Trade secrets often are unpatentable. In that event, there is no
federal policy which is contravened when an injunction to bar
disclosure of a trade secret is issued. Moreover, insofar as
foreign patents are involved, our federal patent policy is
obviously irrelevant. S. Oppenheim, Unfair Trade Practices 264-265

trade secrets,

Licensing, 4 Pat.L.Rev. 375 (1972).
[
Footnote 2/4]
As to
Goldstein v. California, 412 U.
S. 546, the ruling of Mr. Justice Bradley concerning the
distinction between patents and copyright is relevant:
"The difference between the two things, letters-patent and
copyright, may be illustrated by reference to the subjects just
enumerated. Take the case of medicines. Certain mixtures are found
to be of great value in the healing art. If the discoverer writes
and publishes a book on the subject (as regular physicians
generally do), he gains no exclusive right to the manufacture and
sale of the medicine; he gives that to the public. If he desires to
acquire such exclusive right, he must obtain a patent for the
mixture as a new art, manufacture, or composition of matter. He may
copyright his book, if he pleases, but that only secures to him the
exclusive right of printing and publishing his book. So of all
other inventions or discoveries."
