What Qualifies as a Trade Secret Under U.S. Law?

A trade secret is any information that gets its economic value from not being generally known and that the owner takes reasonable measures to keep secret. That is the whole definition, and both halves must be true at the same time. A customer list that anyone could reconstruct from a trade directory fails the first half. A genuinely secret formula that sits on a shared drive every employee can open fails the second. What qualifies as a trade secret is therefore less about the type of information and more about its value and how it is handled, which is why the same document can be a trade secret in one company and ordinary paperwork in another. CLP’s trade secret protection practice starts every engagement by sorting a client’s information into those two tests.

The statutory test for a trade secret

The federal Defend Trade Secrets Act defines a trade secret as all forms and types of financial, business, scientific, technical, economic, or engineering information, in any form, provided that the owner has taken reasonable measures to keep it secret, and the information derives independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable through proper means by, another person who can obtain economic value from its disclosure or use.

Most states apply a near-identical definition under their versions of the Uniform Trade Secrets Act. Virginia and the District of Columbia have both adopted it. New York, as of this writing, has not; its courts apply a common-law definition drawn from the Restatement of Torts, which looks at the same questions through a list of factors: how widely the information is known outside the business, how widely it is known inside, the measures taken to guard it, its value to the business and to competitors, the effort or money spent developing it, and how easily it could be acquired or duplicated by others. The practical analysis is the same under every version.

Information that commonly qualifies

The categories are broad. Technical information: formulas, recipes, manufacturing processes, source code that has not been published, algorithms, chemical compositions, and engineering drawings. Business information: customer lists compiled through effort and not readily available elsewhere, pricing strategies, supplier terms, cost structures, marketing plans, and financial projections. Negative know-how also qualifies: records of approaches that were tried and failed have value because they save a competitor from repeating the mistakes.

What unites these examples is that each took effort to develop, would help a competitor, and can be kept out of public view. A trade secret does not need to be novel in the patent sense, and it does not need to be a single document. A combination of publicly known elements can be a trade secret if the particular combination is not known and has value.

Information that does not qualify

General skills, knowledge, and experience that employees acquire in the course of their work belong to the employee, and an employer cannot claim them as trade secrets. Information that is readily ascertainable through proper means, such as a product’s visible features, a price list distributed to customers, or data published in a trade journal, does not qualify. Information disclosed in a patent application that has published is public, which is why the patent and trade secret routes are exclusive for the same information, a tradeoff our post on trade secret versus patent protection examines.

Information the owner has not protected also fails, regardless of its value. If the formula was emailed to a prospective partner without an NDA, posted in a public repository, or described at a conference, the second half of the test is gone.

How trade secret status is lost

Unlike a patent or a registered copyright, a trade secret has no fixed term. It lasts as long as it stays secret and valuable, which can be indefinitely, and it ends the moment either condition fails. The common ways it ends:

• Publication by the owner, including in marketing materials, patents, or presentations.
• Reverse engineering of a product by a competitor, which is a proper means of acquisition.
• Independent development by someone else who never had access to the secret.
• Disclosure by an employee, contractor, or partner who was not bound by a confidentiality obligation.
• Failure to maintain reasonable measures, such as leaving the information open on shared systems.

The last item is the one most within the owner’s control, and it is the one most often litigated. What courts expect is the subject of our post on reasonable measures to protect a trade secret.

No registration, no examination

There is no government office that registers trade secrets and no certificate to obtain. Protection arises from the facts, which means the owner must be able to prove them later: what the information was, that it had value because it was secret, and what was done to protect it. Companies that will need to enforce a trade secret should document those facts in advance, in an inventory that identifies each category of confidential information, who has access, and under what agreements. That inventory is the first thing a court asks for and the first thing a buyer’s counsel asks for in diligence.

What misappropriation means

A trade secret is enforced against misappropriation: acquisition by improper means (theft, bribery, misrepresentation, breach of a duty to maintain secrecy, or espionage), or disclosure or use without consent by someone who acquired it improperly or who owed a duty of confidence. Independent discovery and reverse engineering are expressly not improper means. Remedies under the DTSA and state law include injunctions, damages for actual loss and unjust enrichment, or a reasonable royalty, with enhanced damages and attorney’s fees available for willful and malicious misappropriation.
