A trade secret is any confidential business information — a formula, method, design, or process — that gives its owner a competitive edge because competitors don’t know it, and that the owner has taken real steps to keep secret. Unlike a patent, a trade secret isn’t registered with any government office and isn’t published; it can, in principle, last forever, but only as long as it stays hidden. The moment a rival can figure it out through honest means, such as reverse-engineering a purchased product, the secret loses its legal protection.
What Counts as a Trade Secret
Courts generally test three things before recognizing information as a trade secret:
- It’s actually secret — not published, not common knowledge in the industry, not something a competitor could piece together from public sources.
- It has economic value because it’s secret — a company’s advantage would shrink if the information became public.
- The owner took reasonable steps to protect it — nondisclosure agreements, restricted internal access, encrypted repositories, exit interviews, and similar controls.
A trade secret can be almost anything: a chemical formula (the classic example is Coca-Cola’s recipe), a customer list, a manufacturing process, source code, or — increasingly, in AI — the architecture of a model, the way a company filters and weights its training data, or the design of a custom chip.
How the Law Protects Trade Secrets
In the United States, trade secret owners can sue under state law (most states have adopted a version of the Uniform Trade Secrets Act) or, since 2016, under the federal Defend Trade Secrets Act, which lets a company bring a civil case directly in federal court. A successful plaintiff can win an injunction stopping the defendant from using the stolen information, damages equal to the losses caused (or the profits the thief made), and — if the theft was willful — extra punitive damages. Deliberate, large-scale theft can also trigger criminal charges under the older Economic Espionage Act of 1996.
Unlike a patent case, a trade secret case isn’t about proving the idea was novel — it’s about proving the information was secret, valuable, and taken improperly, typically by a departing employee who copied files, or a partner who misused confidential material shared for another purpose.
Why AI Companies Keep Landing in Court Over Them
AI development runs on a small pool of specialized engineers who move frequently between a handful of companies — labs, chipmakers, and device teams often hire directly from one another. That mobility is exactly what makes trade-secret disputes common in the industry: a company’s most valuable, hardest-to-replace assets — training techniques, data pipelines, model architectures, custom silicon designs — often live in the heads and laptops of people who then go work for a competitor.
The playbook was set well before generative AI: in 2017, Alphabet’s self-driving unit Waymo sued Uber, alleging that a former engineer downloaded thousands of confidential files on lidar technology before leaving to found a startup Uber quickly acquired. The case settled five days into trial for $245 million in Uber equity. It set the template other companies have followed since: when a founding engineer or research lead crosses to a rival building similar technology, and confidential files are found to have moved with them, a trade secret suit — not a patent suit — is usually the company’s fastest legal option.
In the News
That template is playing out again: Apple has sued OpenAI, accusing two former Apple engineers of taking confidential hardware secrets to help build OpenAI’s in-development consumer device. As with Waymo v. Uber, the dispute centers not on whether OpenAI’s device idea is original, but on whether specific confidential information moved with the engineers who changed employers.
FAQ
Is a trade secret the same as a patent?
No. A patent requires public disclosure and registration and lasts a fixed term (typically 20 years), in exchange for a temporary monopoly. A trade secret is never disclosed or registered and can last indefinitely — but only as long as it stays secret and no one discovers it independently or through reverse-engineering.
Can a company sue a former employee for taking a trade secret to a new job?
Yes, and it’s one of the most common trade-secret scenarios. The employer typically has to show the employee had access to specific confidential information, took it improperly (for example, downloading files before resigning), and that the new employer is using or benefiting from it.
What happens once a trade secret becomes public?
Its legal protection ends. Once information is genuinely public — leaked, published, or independently discovered — courts no longer treat it as a trade secret, even if the leak itself was unlawful.
Does simply hiring someone from a rival count as trade secret theft?
No. Hiring a competitor’s employees is legal, and using the general skills and know-how a person built up over a career isn’t theft. Liability turns on whether the person brought specific confidential material — documents, code, designs — that belonged to the former employer.
