Pennsylvania Trade Secret Laws: UTSA, Remedies & Deadlines
Pennsylvania enacted the Pennsylvania Uniform Trade Secrets Act (PUTSA), codified at 12 Pa. C.S. §§ 5301 to 5308, in 2004, replacing decades of common-law trade secret protection with a unified statutory framework. Civil claims for misappropriation must be brought within three years from the date the misappropriation was discovered, or reasonably should have been discovered.

Does Pennsylvania Have a Trade Secret Law?
Pennsylvania enacted the Pennsylvania Uniform Trade Secrets Act in 2004, codified at 12 Pa. C.S. §§ 5301 to 5308, effective December 17, 2004. PUTSA is modeled on the Uniform Trade Secrets Act (UTSA) developed by the Uniform Law Commission. Before PUTSA, Pennsylvania relied on common-law trade secret principles drawn from the Restatement of Torts, which meant that protection depended on the evolving body of Pennsylvania case law rather than a codified statute. PUTSA replaced those common-law claims with a unified statutory framework, providing defined elements, predictable remedies, and express preemption of conflicting tort claims. PUTSA applies only to misappropriation occurring on or after its effective date; earlier misappropriation continues to be governed by pre-2004 common law. Pennsylvania courts look to UTSA commentary and to decisions from other UTSA-adopting states as persuasive authority.
What Counts as a Trade Secret and Misappropriation Under PUTSA?
Under 12 Pa. C.S. § 5302, a trade secret is information, including a formula, drawing, pattern, compilation, program, device, method, technique, or process, that satisfies two requirements. First, the information must derive independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use. Second, the information must be the subject of efforts that are reasonable under the circumstances to maintain its secrecy.
Pennsylvania courts evaluate reasonableness by looking at the totality of the owner's protective measures. Recognized steps include requiring employees, contractors, and partners to sign nondisclosure agreements; restricting access to sensitive systems and files on a need-to-know basis; marking materials as proprietary or confidential; conducting security training; and implementing technical safeguards such as access controls and encryption. A business need not adopt every possible measure, but must demonstrate a genuine and consistent effort to maintain secrecy.
Misappropriation under § 5302 means acquiring a trade secret by improper means, including theft, bribery, misrepresentation, breach or inducement of a breach of a duty to maintain secrecy, or espionage. Misappropriation also means disclosing or using a trade secret without consent when the discloser acquired it through improper means, knew or had reason to know the secret was obtained through improper means, or had a specific duty of secrecy and breached it. Section 5302 confirms that reverse engineering and independent development are proper means and therefore do not constitute misappropriation under PUTSA.
Remedies and the Limitations Period Under PUTSA
A civil misappropriation claim under PUTSA must be brought within three years from the date the claimant discovered, or by the exercise of reasonable diligence should have discovered, the misappropriation. The three-year period aligns with the UTSA baseline and the federal DTSA's limitations period under 18 U.S.C. § 1836(d). Pennsylvania applies a discovery rule, so the clock begins when the owner knew or had reason to know that misappropriation occurred, not necessarily when the underlying act took place. Claims based on misappropriation that occurred before December 17, 2004 remain subject to Pennsylvania's pre-PUTSA common-law rules.
Available remedies under PUTSA include:
- Injunctive relief (12 Pa. C.S. § 5303): A court may enjoin actual or threatened misappropriation and may extend an injunction to eliminate any commercial advantage derived from the misappropriation. Where an injunction would be inequitable, the court may permit continued use subject to payment of a reasonable royalty.
- Damages (§ 5304): A prevailing claimant may recover actual loss caused by the misappropriation plus unjust enrichment not captured in the actual-loss figure. Where neither measure is provable with sufficient certainty, the court may award a reasonable royalty for the unauthorized disclosure or use.
- Exemplary damages (§ 5304): When the misappropriation is willful and malicious, the court may award exemplary damages up to twice the compensatory damages.
- Attorney fees (§ 5305): Available to the prevailing party when a claim of misappropriation is made in bad faith, when a motion to terminate an injunction is made or resisted in bad faith, or when willful and malicious misappropriation is found.
Under 12 Pa. C.S. § 5307, PUTSA displaces conflicting civil claims for misappropriation of a trade secret, channeling those disputes to the statutory framework. Contract claims, criminal liability, and civil remedies not based on misappropriation are unaffected.
How the Federal DTSA Applies in Pennsylvania
The Defend Trade Secrets Act, 18 U.S.C. §§ 1836-1839, enacted in May 2016, creates a federal civil cause of action for trade secret misappropriation when the secret relates to a product or service used in, or intended for use in, interstate or foreign commerce. The DTSA does not preempt PUTSA (18 U.S.C. § 1838), so Pennsylvania trade-secret owners may plead both statutes simultaneously, commonly in federal district court.
Key DTSA provisions applicable in Pennsylvania:
- Limitations: three years from discovery (18 U.S.C. § 1836(d)), identical to the state period under PUTSA.
- Remedies: injunctive relief, actual damages plus unjust enrichment or a reasonable royalty, exemplary damages up to twice the compensatory award for willful and malicious misappropriation, and attorney fees for bad-faith claims or willful and malicious conduct (§ 1836(b)(3)).
- Ex parte seizure: in extraordinary circumstances a federal court may authorize seizure of property to prevent propagation or dissemination of a trade secret (§ 1836(b)(2)).
- Whistleblower immunity and notice: individuals who confidentially disclose a trade secret to a government official or attorney to report a suspected legal violation are immune from DTSA and state trade-secret liability (§ 1833(b)(1)). Confidentiality or nondisclosure agreements signed or updated after May 11, 2016 must include written notice of this immunity; omitting it forfeits the right to exemplary DTSA damages and attorney fees in any action tied to that agreement (§ 1833(b)(3)).
Criminal trade-secret theft in Pennsylvania may also be prosecuted under the federal Economic Espionage Act, 18 U.S.C. §§ 1831-1832.

Frequently Asked Questions
What qualifies as a trade secret under Pennsylvania law?
Under 12 Pa. C.S. § 5302, information qualifies as a trade secret if it derives independent economic value from not being generally known or readily ascertainable by proper means, and if the owner takes efforts reasonable under the circumstances to maintain its secrecy. Protected information may include formulas, drawings, patterns, compilations, programs, devices, methods, techniques, and processes.
How long do I have to file a trade secret lawsuit in Pennsylvania?
Pennsylvania's Uniform Trade Secrets Act provides a three-year limitations period running from the date you discovered or reasonably should have discovered the misappropriation. The same three-year period applies under the federal Defend Trade Secrets Act (18 U.S.C. § 1836(d)). Note that PUTSA applies only to misappropriation occurring on or after December 17, 2004; older claims are governed by Pennsylvania common law.
What remedies are available for trade secret misappropriation in Pennsylvania?
PUTSA provides injunctive relief, damages for actual loss plus unjust enrichment or a reasonable royalty, up to twice the compensatory damages for willful and malicious misappropriation, and attorney fees when a claim or defense is made in bad faith or the misappropriation is willful and malicious (12 Pa. C.S. §§ 5303-5305).
Do nondisclosure agreements help protect trade secrets in Pennsylvania?
Yes. Pennsylvania courts consider whether the owner took reasonable efforts to maintain secrecy, and a well-drafted NDA is strong evidence of those efforts. Under the federal DTSA, any NDA or confidentiality agreement signed or updated after May 11, 2016 must include a whistleblower-immunity notice, or the employer forfeits the right to seek exemplary DTSA damages and attorney fees in a federal action tied to that agreement.
Can Pennsylvania businesses bring both a PUTSA claim and a federal DTSA claim?
Yes. The DTSA does not preempt PUTSA (18 U.S.C. § 1838), so Pennsylvania trade-secret owners may assert both claims in the same lawsuit, typically in federal district court when the misappropriation involves interstate or foreign commerce. Both carry a three-year limitations period from discovery, and the remedial frameworks are substantially parallel.
