Your source code, your algorithms, your customer data, your manufacturing process: for a Silicon Valley company, that information is often worth more than any physical asset you own. When it needs protection, or when someone takes it, a San Jose trade secrets lawyer is the one you call.
Our trade secrets and intellectual property law firm works with founders, engineering leads, and operations managers across San Jose and the wider Bay Area.
Trade-secret disputes often involve highly technical information, including source code, algorithms, semiconductor processes, hardware designs, manufacturing methods, and engineering specifications.
Heimlich Law brings more than 20 years of engineering experience to intellectual property practice, enabling us to understand complex technologies and help businesses identify information that may qualify for trade secret protection.
This front-end judgment is where the value is created, often keeping a theft from becoming a lawsuit.
Trade-secret disputes require careful evidence preservation, confidentiality planning, and litigation strategy from the outset. Whether pursuing or defending a claim, we tailor our approach to the facts of the case while protecting sensitive business information throughout the litigation process.
For active matters, our trade secret litigation practice handles trade-secret disputes in California state and federal courts.
Not every trade-secret dispute involves a company that has been wronged. Businesses can also face allegations after hiring employees from competitors, developing similar technologies independently, or receiving broad claims that fail to identify a protectable trade secret. We help clients assess the strength of those claims, preserve relevant evidence, and build a practical defense while minimizing disruption to their business.
Two requirements are central under CUTSA. The information must derive independent economic value from not being generally known, and the owner must take reasonable measures under the circumstances to maintain its secrecy. Both have to be met. Information that fails either test is not a trade secret, no matter how sensitive the business considers it.
Confidential information is not automatically a trade secret. A company can stamp a document “confidential” and still have no claim if the information carries no independent economic value from secrecy, or it never took reasonable steps to protect it. Status turns on the facts, not the label.
Many categories of business information can qualify: source code and algorithms, semiconductor and IC processes, hardware and circuit designs, technical know-how and engineering specifications, customer and supplier information, pricing and cost data, and business strategies. Formulas and manufacturing processes can qualify too. These are examples, not guarantees. A customer list is protected only when it meets both requirements. The legal test controls, not the category.
Two practical dimensions decide if those requirements hold up.
For a deeper look at the qualifying standard, see our guide on what qualifies as a trade secret in California. The next section addresses the trade-secret-versus-patent choice directly; for the broader picture across patents, copyrights, and trademarks, our intellectual property attorney can map how each fits your situation.
Trade secrets and patents protect innovation in opposite ways, and choosing the wrong one can cost you protection. The choice between patent and trade-secret protection can have significant consequences, particularly if public disclosure occurs before a patent application is filed. A utility patent requires public disclosure that meets patent law requirements in exchange for a limited term of exclusive rights, generally 20 years from the relevant U.S. filing date, subject to patent-term adjustment, extension, and other exceptions , after which the invention enters the public domain.
A trade secret is the reverse: keep it confidential and protection can last indefinitely, but only until the information is independently developed, lawfully reverse-engineered, or otherwise disclosed. It requires no government registration and lasts as long as the information remains secret and the legal requirements are met.
The decisive question: can competitors lawfully learn the innovation from the product itself?
|
FACTOR |
TRADE SECRET |
PATENT |
|
Can competitors learn it through lawful reverse engineering? |
Poor fit if yes, since reverse engineering defeats the secret |
Often stronger protection if yes, since the patent still controls |
|
How long is it valuable? |
Indefinitely, if kept secret |
A defined window is enough |
|
Does public disclosure benefit you? |
No, secrecy is the whole value |
Yes, published rights let you license and enforce broadly |
|
Is it patentable subject matter? |
Not required |
Must meet novelty and non-obviousness |
|
Example |
Internal process a product does not reveal |
Novel device a competitor could copy from the product |
The innovation stays hidden inside your operation and cannot be learned from the product itself. Secrecy can then outlast any patent, and a formula kept quiet for over a century is the classic example.
A competitor could reverse-engineer the innovation from the product the moment it ships. Trade-secret law offers nothing against someone who lawfully figures it out, so a patent’s public rights protect you better. Make the call before you disclose anything.
Protection is a layered program, and its strength is measured by what you did, not what your policies say. The key elements work together:
That last element matters more than it looks, because you will eventually have to identify your secrets with precision. We work with San Jose companies to audit their existing assets and document their measures, so they hold up in court.
Employee departures are a common source of trade-secret disputes, especially where job changes are frequent. Early steps shape what follows:
The core legal question is distinguishing an employee’s general knowledge and skills, which they remain free to use, from identifiable trade secrets they cannot. That line decides many cases, though qualification, secrecy measures, improper acquisition, use, causation, and damages can all be contested.
Business and Professions Code section § 16600 voids employee noncompete agreements, and amendments effective January 1, 2024, made a void agreement unenforceable wherever and whenever it was signed, with narrow exceptions for the sale or dissolution of a business. Trade-secret law does not fill that gap as a substitute for a noncompete, so an employer cannot use a trade-secret claim simply to keep a former employee from joining a competitor.
Business and Professions Code sectiont §16600.1 separately prohibits inclusion of noncompete clauses that do not satisfy an exception and imposed a 2024 notice requirement for certain existing agreements.
California does not recognize the “inevitable disclosure” doctrine either. In Whyte v. Schlage Lock Co., an appellate court rejected it as an after-the-fact restraint on mobility. That does not bar relief for genuinely threatened misappropriation, which California courts still allow where the right facts are present. You cannot stop a former employee from a new job by arguing they will inevitably use what they know, but you can act on actual or threatened misappropriation of a protectable trade secret. Our overview on protecting trade secrets when employees leave covers this in more depth.
The response steps above turn on a term worth defining precisely. Under CUTSA, misappropriation means acquiring a trade secret through improper means, or disclosing or using it without consent when you knew or should have known it was acquired improperly. Improper means includes theft, bribery, misrepresentation, breach or inducement of a breach of a duty to keep information secret, and espionage.
Trade-secret law does not reach information obtained through legitimate channels, including independent development, lawful acquisition from a source entitled to disclose it, and reverse engineering of a lawfully obtained product where permitted. If a competitor independently develops the same process or lawfully reverse-engineers your product, you generally have no trade-secret claim because no improper means was used. That limit is one of the key reasons some innovations are better protected by patents.
California trade-secret litigation follows procedures designed to define and protect the information at issue. Under California Code of Civil Procedure section 2019.210, a party alleging misappropriation under CUTSA must identify the claimed trade secret with reasonable particularity before discovery related to it begins. A plaintiff cannot file a vague complaint and use discovery to determine what was taken. The trade secret must be described specifically enough to distinguish it from general knowledge in the field and give the defendant fair notice of the claim. Defendants frequently challenge those descriptions, so getting them right early often shapes how the case proceeds.
Businesses often worry that filing suit will expose the very information they are trying to protect. California law addresses that concern. California Civil Code section 3426.5 authorizes courts to preserve the secrecy of alleged trade secrets through protective orders, in camera hearings, and sealed records, allowing owners to enforce their rights without publicly disclosing the information.
Everything above rests on two statutes. California has two trade-secret regimes that operate side by side, not as alternatives.
FEATURE | CALIFORNIA UNIFORM TRADE SECRETS ACT (CUTSA) | DEFEND TRADE SECRETS ACT (DTSA) |
Source of law | State law, Civil Code sections 3426 to 3426.11 | Federal law, 18 U.S.C. sections 1836 to 1839 |
Court | California state courts | Federal courts |
Scope | Trade secrets under California law | Trade secrets related to a product or service used in, or intended for use in, interstate or foreign commerce |
Enacted | 1984 | 2016 |
Statute of limitations | Three years from discovery | Three years from when the misappropriation is discovered or, by exercise of reasonable diligence, should have been discovered. |
The DTSA gave owners direct access to federal court without needing diversity jurisdiction, and it can run alongside a California claim when the facts and jurisdictional requirements support both.
One DTSA detail catches employers off guard. The statute requires notice of its whistleblower immunity in agreements governing trade secrets or confidential information entered into or updated after May 11, 2016, and contractors count as “employees” for this purpose. Fail to give the notice, and you cannot recover exemplary damages or attorney’s fees under the DTSA against an employee who did not receive it. The notice can cross-reference a policy document (the policy must set forth the employer’s reporting policy for suspected violations of law) rather than reciting the provision in full, a small drafting step with a real consequence worth a review of your agreements.
California and federal law both offer several remedies, and more than one can be pursued at once. Under CUTSA:
The federal DTSA offers a parallel set of remedies. It adds one California courts lack: in extraordinary circumstances, a court may order the ex parte seizure of property necessary to prevent the dissemination or use of a trade secret, subject to strict statutory requirements. It is a rare, demanding remedy for cases where evidence faces genuine risk. Which remedies fit depends on the facts, one of the first things we assess.
Often, yes. Trade-secret protection does not depend on a signed agreement. If the information met the legal test and was taken through improper means, you may have a claim even without an NDA, though a written agreement makes proof much easier.
Yes, when they meet the standard. Source code, model weights, training data, and architecture can all qualify if they carry independent economic value from secrecy and you guard them with reasonable measures. Secrecy is often the practical route for software that a patent would force you to disclose.
Generally no. California favors employee mobility and rejects the inevitable disclosure doctrine, so knowing your information is not enough to block a new job. You must show actual or threatened misappropriation of an identifiable trade secret.
Fast. Where misuse is underway or imminent, courts can grant a temporary restraining order within days. Delay both increases the harm and weakens the argument that the matter is urgent, so an early call to counsel matters.
Preserve logs, access records, emails, and device data immediately, and avoid altering the source systems, since chain of custody can decide the case.
