What Is a Trade Secret? Protection, Theft, and the Law

What Is a Trade Secret?

A trade secret is any confidential business information that provides a competitive advantage and is subject to reasonable efforts to keep it secret. Unlike patents, trademarks, and copyrights — which require registration with a government agency — trade secret protection exists automatically as long as the information remains confidential and the owner takes reasonable steps to protect it.

Famous examples: the Coca-Cola formula (kept secret since 1886, held in a vault at the World of Coca-Cola museum), KFC's "11 herbs and spices," Google's search ranking algorithm, and the exact formulations of countless pharmaceutical, chemical, and food products.

What Qualifies as a Trade Secret?

Under the Defend Trade Secrets Act (DTSA) — the primary federal trade secret law since 2016 — a trade secret is information that:

1. Has independent economic value from not being generally known or readily ascertainable by competitors
2. The owner takes reasonable measures to protect — secrecy is actively maintained

Examples of qualifying trade secrets: customer lists and pricing strategies, manufacturing processes and formulas, software source code, research and development data, business plans and financial projections, marketing strategies, and supplier information.

Public information, independently developed information, and information properly obtained through reverse engineering cannot be trade secrets.

Trade Secrets vs. Patents

• Trade secrets: No registration, no disclosure required, no expiration (as long as secrecy is maintained), protection depends on continued secrecy. Can be lost if independently discovered or reverse-engineered.
• Patents: Require public disclosure of the invention, 20-year protection, then public domain. Prevent independent development — even if someone independently invents the same thing, they infringe the patent.

Companies strategically choose between them. Coca-Cola chose trade secret protection because 20-year patent protection would have expired decades ago; pharmaceutical companies choose patents because they cannot prevent reverse engineering of drug compounds through secrecy.

Protecting Trade Secrets

"Reasonable measures" is the legal standard — courts look at what the company actually did to protect the information:

• Non-disclosure agreements (NDAs): Requiring employees, contractors, and partners to sign NDAs before accessing confidential information
• Employee agreements: Employment contracts with confidentiality provisions; non-compete agreements (though enforceability varies by state)
• Physical security: Restricted access to sensitive areas, locked storage for documents
• Digital security: Access controls, encryption, need-to-know basis for sensitive information, monitoring systems
• Exit procedures: Reminding departing employees of their obligations, revoking access immediately

Companies that fail to take reasonable measures can lose trade secret protection — a court may find the information wasn't actually secret if the company treated it carelessly.

Trade Secret Theft

Misappropriation of trade secrets includes acquiring them through improper means (hacking, bribery, breach of duty) or using/disclosing a secret known to have been misappropriated. Remedies include injunctions, damages (actual losses plus unjust enrichment), and in egregious cases, exemplary damages (up to 2× actual damages) and attorney fees.

Federal criminal law — the Economic Espionage Act — makes trade secret theft a federal crime, with penalties up to 15 years imprisonment for individuals and $5 million for organizations, and up to 20 years for theft benefiting a foreign government (economic espionage).
