Trade secret protection is the only form of intellectual property you can lose by neglect. A patent stays valid whether or not you guard it. A trade secret exists only as long as it is secret and you can prove in court that you took reasonable measures to keep it that way. Companies discover the second half of that sentence during litigation, when a judge asks who had access to the file and nobody can answer.

What legally qualifies as a trade secret

Under the federal Defend Trade Secrets Act (DTSA) and the state versions of the Uniform Trade Secrets Act adopted in nearly every state, information qualifies if three things are true:

  1. It is not generally known or readily ascertainable by others who could profit from it.
  2. It derives independent economic value from that secrecy.
  3. The owner has taken measures that are reasonable under the circumstances to keep it secret.

The category is broad: process parameters, tooling settings, supplier lists, cost models, firmware algorithms, test fixtures, customer data, formulations, yield data. It is not limited to formulas. What matters is that the information gives you an edge precisely because competitors do not have it.

Element three is the whole game. Elements one and two are usually obvious from the facts. Element three is where cases are won and lost, and it is entirely within your control.

What counts as reasonable measures

Courts look for a coherent program, not perfection. A small company is not expected to run a defense contractor's security apparatus — but it is expected to do something deliberate. A workable program has six parts.

1. Identify and inventory

Write down what you consider secret. A short document listing categories — process settings for the molding line, the BOM cost file, the calibration algorithm, the supplier agreement terms — is enormously persuasive later. You cannot claim protection over "everything we know." Courts have rejected exactly that.

2. Mark and segregate

Label documents and files as confidential. Keep secret material in named locations rather than scattered across shared drives and personal laptops. Marking is weak evidence on its own and strong evidence in combination with access control.

3. Limit access to need-to-know

This is the measure with the most weight. If every employee and every vendor can open the file, secrecy is hard to argue. Role-based permissions, logged access, and separate repositories for the sensitive material do most of the work. On the product side the same logic applies to firmware — secure boot and firmware encryption is what keeps a shipped device from handing your algorithm to anyone with a programmer.

4. Get the agreements signed

Employees need invention-assignment and confidentiality provisions from day one, not from the day they resign. Contractors, engineering firms, molders, and contract manufacturers all need NDAs specific enough to name the categories of information. Note one DTSA quirk: employee and contractor agreements should include the whistleblower immunity notice, or you forfeit exemplary damages and attorney fees against that person. When an NDA actually protects your idea covers where these agreements are strong and where they are theater.

5. Control the exits

Offboarding is when most trade secrets walk. A documented exit interview, a signed acknowledgment of continuing obligations, prompt revocation of accounts, and a return-of-materials confirmation take twenty minutes and are cited in court constantly. Be aware that non-compete enforceability varies sharply by state and several states bar them outright, so lean on confidentiality obligations rather than non-competes.

6. Control the supply chain

The highest-risk moment for a hardware company is sending a full data package to a manufacturer. Practical mitigations: split the work so no single vendor holds the complete recipe, keep the critical process step in-house or with a vendor under a stronger agreement, withhold the master CAD and send only what each supplier needs, and choose jurisdictions where you could actually enforce. Who owns the IP a contractor creates and employee invention rules both matter here, because ownership disputes and secrecy disputes usually arrive together.

What trade secret law does not stop

Two lawful routes around a trade secret exist and no agreement can close them:

  • Independent development. If a competitor figures it out on their own, you have no claim.
  • Reverse engineering. Buying your product and taking it apart is legal in the United States. Anything visible in a teardown — geometry, materials identifiable by analysis, board layout — is not realistically a secret.

That single fact is what makes the patent-versus-secrecy decision concrete: secrets work for things buried in a process, not for things sitting in the customer's hand. The trade secret versus patent comparison works through the decision, and it is worth noting that a manufacturing method can sometimes be patented instead — see patenting a process rather than a product.

Enforcement, and what you get

The DTSA created a federal civil cause of action for misappropriation, which means you can sue in federal court without a diversity hook. Remedies include injunctive relief, actual loss plus unjust enrichment or a reasonable royalty, and up to double damages plus fees for willful and malicious misappropriation. There is also an ex parte civil seizure remedy for extraordinary circumstances, used sparingly. The limitations period is three years from when the misappropriation was discovered or should have been discovered.

Realistically, the first move in a misappropriation case is a preliminary injunction, and it turns on evidence you either created in advance or did not. Access logs, signed agreements, marked documents, and a written inventory are what convert a strong instinct into a granted order.

Build the program around the product

For a hardware company the secrecy program should follow the actual value: usually the process window, the calibration data, the test fixture, and the cost structure — rarely the shape of the housing. Map those onto a broader plan rather than treating each in isolation; building an IP protection strategy around a product shows how patents, secrets, trademarks, and contracts divide the work.

Projects House is an engineering firm, not a law firm, and the agreements and litigation strategy belong with counsel. Where we help is the engineering side of secrecy: partitioning a design so no single supplier holds the whole recipe, keeping the critical process step controllable, and structuring documentation so a manufacturer gets what it needs and nothing more.
