Takeaway

In short, this case holds that federal patent law generally does not preempt state trade-secret law because secrecy protection against misappropriation coexists with, rather than frustrates, the patent system's limited-monopoly-for-disclosure bargain.

Background

Harshaw Chemical Co., a division of Kewanee Oil, developed processes and manufacturing techniques for producing large synthetic sodium-iodide crystals used to detect ionizing radiation. After spending more than $1 million on research, Harshaw could grow 17-inch crystals. It treated many of its methods as trade secrets and required employees to agree not to disclose confidential information or trade secrets.

Several former Harshaw employees formed or joined Bicron, a competing crystal manufacturer. Bicron soon produced a 17-inch crystal. Kewanee brought a diversity action in federal district court, alleging that the former employees had misappropriated Harshaw's trade secrets. Applying Ohio law, the District Court permanently enjoined respondents from using or disclosing 20 trade secrets until the information became public, generally available, or was lawfully obtained from another source.

The Sixth Circuit accepted the District Court's factual findings and agreed that respondents had taken secret process information. But it reversed because it believed Ohio trade-secret law conflicted with federal patent law: the processes were patentable subject matter, yet commercial use for more than one year had made them ineligible for a federal patent. The Supreme Court reversed the Sixth Circuit and directed reinstatement of the District Court's judgment.

Issues

Issue #1

Whether the Constitution's Patent Clause prevents States from protecting discoveries through trade-secret law.

Holding

No. The Patent Clause does not itself bar States from regulating and protecting intellectual property relating to discoveries, so long as state law does not conflict with federal patent law.

Reasoning

Article I gives Congress power to promote science and useful arts by granting exclusive rights to inventors, but that grant is not exclusive. Drawing on Goldstein v. California, the Court held that States retain authority to protect intellectual achievements, including discoveries, unless Congress has displaced state regulation or the state rule conflicts with federal law.

State trade-secret protection therefore cannot be invalidated merely because trade secrets may include processes or techniques that could fall within patentable subject matter. The controlling question under the Supremacy Clause is instead whether Ohio's particular trade-secret regime frustrates the purposes and objectives of the federal patent system.

Issue #2

Whether federal patent law preempts Ohio trade-secret law protecting secret processes and manufacturing techniques, including information that could have been patented but was not.

Holding

No. Ohio trade-secret law is not preempted because it does not materially obstruct the patent system's incentives for invention, disclosure, or preservation of the public domain.

Reasoning

Patent law gives a qualifying inventor a time-limited right to exclude others in exchange for public disclosure. It also ensures that matter already in the public domain remains freely available. Trade-secret law serves different but compatible ends: it promotes commercial ethics, deters theft and breaches of confidence, and encourages investment in research and development.

A trade secret protects only information that remains secret. It does not prevent independent invention, reverse engineering, accidental discovery, or other fair means of acquisition. Thus, unlike a patent, it does not remove publicly available ideas from the public domain or confer a right good against the world.

For subject matter outside the patent statute, eliminating trade-secret protection would not produce patent disclosures because no patent could issue in any event. Protection for such information as customer lists, business plans, and other nonpatentable know-how can encourage productive competition without displacing any federal patent policy.

Trade-secret protection for inventions known or believed not to satisfy patentability standards also does not significantly impair patent-law disclosure. Requiring inventors to file applications they expect to fail would not add useful information to the public record, because pending and abandoned patent applications were confidential. Meanwhile, trade-secret protection encourages development and licensing of useful but unpatentable know-how.

Without legal protection against disloyal employees, licensees, and industrial espionage, innovators would resort to costly self-help: tighter internal security, restricted sharing of information, and greater concentration of knowledge in a few trusted employees. Those costs would burden smaller firms especially and discourage licensing, thereby reducing rather than promoting the efficient dissemination and use of valuable information.

For inventions of doubtful patentability, the availability of trade-secret law may sometimes lead an inventor not to seek a patent. But eliminating that alternative would also induce applications for inventions that ultimately are not patentable, creating delay and potentially increasing the risk that invalid patents will issue. The Court found the speculative gain in disclosure insufficient to outweigh these costs.

For clearly patentable inventions, the Court concluded that trade-secret law poses no realistic threat to the disclosure bargain of patent law. Patent protection is substantially stronger because it lasts against everyone, including independent inventors and reverse engineers, while trade-secret protection can be lost through lawful discovery or disclosure. An inventor who reasonably expects a valid patent will ordinarily prefer the patent's stronger protection.

The Court rejected partial preemption limited to inventions that should have been patented. That approach would require state courts to decide, often without a patent application's specifications or the Patent Office's analysis, whether an unpatented and still-secret discovery was clearly patentable. The resulting inquiry would be both difficult and impractical.

Trade-secret and patent protection had coexisted for more than a century, and Congress had not affirmatively displaced state trade-secret law. Because Ohio's law neither removes public-domain ideas from public use nor creates a substantial disincentive for inventors to seek patents, complete or partial preemption was unwarranted.

Concurrences

Justice Marshall

Reasoning

Justice Marshall agreed that Ohio trade-secret law was not preempted, but he rejected the majority's view that a patentable inventor's reliance on trade-secret protection is “remote indeed.” In his view, trade-secret protection can be quite attractive to an inventor who plans to make or sell the invention personally rather than license it, because secrecy can provide protection of unlimited duration rather than the patent law's 17-year term.

Marshall believed that trade-secret law can therefore create a meaningful disincentive to patenting and can deprive the public of disclosure. But he treated the question as one of congressional intent, not preferred policy. Congress had long known that state trade-secret regimes existed, had not shown disapproval, and had sometimes expressly protected confidential trade-secret information submitted to federal agencies. That history showed neither an actual conflict making both systems impossible nor a congressional decision to preempt the field.

Dissents

Justice Douglas

Reasoning

Justice Douglas, joined by Justice Brennan, maintained that the decision conflicted with Sears and Compco. Those cases establish that articles not protected by a valid patent belong in the public domain and cannot receive state-law protection that effectively supplies the exclusive rights federal patent law withheld.

Harshaw's manufacturing techniques were patentable subject matter, yet Harshaw did not seek a patent and therefore did not make the full disclosure that patent law demands in exchange for a limited monopoly. The injunction nevertheless gave Harshaw an effectively perpetual right to prevent these former employees from using the secret processes. In Douglas's view, that result lets state law provide a stronger and longer monopoly than federal patent law permits.

Douglas distinguished damages for theft or breach of a confidential relationship from an injunction against use or disclosure. A damages remedy addresses the wrong of violating confidence and need not be preempted. But an injunction enforcing continued secrecy operates as a patent-like monopoly; it is preempted when applied to patentable inventions because it evades patent law's disclosure-for-limited-exclusivity bargain.

The dissent viewed the constitutional and statutory patent policy as an affirmative choice favoring public disclosure and the free exchange of technological information. The Court should enforce that choice rather than substitute its own assessment that secrecy may produce useful economic benefits.
