Key Takeaways
- The California Uniform Trade Secrets Act (CUTSA) can preempt overlapping noncontract claims such as intentional interference and conversion at the pleading stage.
- Courts will sustain demurrers if alternative causes of action rely on the same "nucleus of facts" as the trade secret misappropriation claim.
- Computer-access claims under Penal Code section 502 or the CFAA may also be displaced if they are based on alleged misuse rather than genuinely unauthorized access.
- To survive a demurrer, plaintiffs must articulate legally distinct theories supported by separate duties or injuries.
- Tajima LLP recently secured multiple demurrer victories in Los Angeles Superior Court by successfully arguing CUTSA preemption against overlapping business torts.
The Pleading Problem in Trade Secret Cases
California trade secret cases are often pleaded broadly. A complaint may start with a claim for misappropriation of trade secrets and then add related causes of action for intentional interference, conversion, breach of fiduciary duty or duty of loyalty, unfair competition, computer access statutes, and negligence or declaratory relief.
That approach is understandable from a pleading perspective, but it raises a recurring issue under the California Uniform Trade Secrets Act (CUTSA): when do noncontract claims merely restate the same alleged wrong? CUTSA does not eliminate every noncontract claim that appears in the same lawsuit. But where another cause of action depends on the same nucleus of facts as the trade secret theory, preemption may narrow the case substantially.
Recent Demurrer Rulings in Los Angeles Superior Court
A recent set of public demurrer rulings in a Los Angeles County Superior Court, Torrance Courthouse matter provides a useful reminder of how CUTSA preemption can shape California trade secret cases at the pleading stage. Tajima LLP, a Los Angeles complex business litigation boutique, represented the defendants in this matter.
The case involved allegations concerning confidential business information, patient-related information, and related competitive conduct. What makes the rulings noteworthy is not the underlying dispute itself, but the court's treatment of overlapping claims pleaded alongside a trade secret cause of action.
The rulings discussed or relied on familiar CUTSA preemption authorities, including Civil Code sections 3426 through 3426.11, Civil Code section 3426.7(b), K.C. Multimedia, Inc. v. Bank of America Technology & Operations, Inc. (2009) 171 Cal.App.4th 939, Silvaco Data Systems v. Intel Corp. (2010) 184 Cal.App.4th 210, and Angelica Textile Services, Inc. v. Park (2013) 220 Cal.App.4th 495.
Second Amended Complaint Stage
The court sustained the demurrer to claims for intentional interference with prospective economic advantage, conversion, and breach of duty of loyalty, concluding those claims arose from the same nucleus of facts as the trade secret claim.
Third Amended Complaint Stage
The court again sustained the demurrer to a California Penal Code section 502 / UACA claim, holding that it too was displaced by CUTSA because it was based on the same factual core as the trade secret allegations. The court also sustained the demurrer to the CFAA claim, reasoning that the pleading described authorized access and alleged misuse of information rather than the kind of unauthorized access the statute targets.
At the same time, not every non-trade-secret theory fell away. The rulings left room for the proposition that some claims may survive where they are supported by sufficiently distinct facts and duties.
Why These Rulings Matter for Business Litigation
These rulings illustrate a practical point that often gets lost in trade secret pleadings: the real question is not whether a plaintiff can label multiple theories, but whether those theories are actually factually distinct. That distinction matters for several reasons.
1. CUTSA Preemption Is a Powerful Narrowing Doctrine
Lawyers sometimes treat CUTSA preemption as a background issue. In practice, it can be outcome-shaping at the demurrer stage. Where the complaint repeatedly points back to the same alleged taking, use, or retention of information, the court may treat overlapping tort or statutory theories as displaced.
2. Computer-Access Claims Are Not Always a Substitute
The rulings also underscore the importance of separating unauthorized access from authorized access followed by alleged misuse. Courts continue to scrutinize efforts to transform misuse-of-information allegations into hacking-style claims under the CFAA or related statutes.
3. Distinct Duties May Preserve Distinct Claims
The rulings are equally instructive in the other direction. Not every claim touching the same general subject matter is necessarily preempted. If a claim rests on a separate duty, separate injury, or a genuinely different factual predicate, it may survive even in a trade secret-centered case.
Practical Drafting Lessons
Trade secret litigation in California often turns less on how many claims appear in the caption and more on whether the pleading identifies legally distinct theories supported by distinct facts. These public rulings from the Torrance Courthouse are a useful example of that principle in practice.
For plaintiffs: Identify what information is alleged to be the trade secret. Distinguish clearly between trade secret misuse and other alleged misconduct. Articulate separate duties and injuries where non-CUTSA claims are asserted. Avoid relying on conclusory overlap between all causes of action.
For defendants: Test whether noncontract claims depend on the same factual core as the trade secret claim. Examine whether computer-access claims are really access claims or misuse claims. Focus on whether the complaint alleges distinct facts, not just different labels.
For lawyers handling business-to-business or business-to-employee disputes, the lesson is straightforward: in a trade secret case, overlap is not harmless. If multiple causes of action rise or fall on the same alleged conduct, CUTSA preemption may become one of the most important issues in the case.
Key CUTSA Preemption Authorities
Frequently Asked Questions About CUTSA Preemption
What is CUTSA preemption in California trade secret cases?
CUTSA preemption is a legal doctrine under the California Uniform Trade Secrets Act (Civil Code sections 3426–3426.11) that displaces or preempts other noncontract civil claims—such as conversion, intentional interference, or breach of duty of loyalty—when those claims are based on the same factual allegations as a trade secret misappropriation claim. If overlapping tort claims rely on the same nucleus of facts as the trade secret theory, California courts will typically sustain a demurrer and dismiss those claims.
Can a plaintiff sue for both trade secret misappropriation and conversion in California?
Generally, no. If the conversion claim is based on the same taking of confidential information alleged in the trade secret claim, California courts will likely dismiss the conversion claim at the demurrer stage due to CUTSA preemption. To survive, the conversion claim must rely on distinct facts or separate duties that are genuinely different from the trade secret allegations.
How does Tajima LLP defend against broad trade secret claims in California?
Tajima LLP is a Los Angeles business litigation firm that aggressively utilizes pleading challenges, including demurrers based on CUTSA preemption, to narrow the scope of trade secret lawsuits early in the litigation process. By identifying overlapping claims that depend on the same factual core as the trade secret theory, Tajima LLP forces plaintiffs to rely strictly on legally distinct and factually supported theories, often resulting in the dismissal of multiple causes of action before discovery.
What California cases address CUTSA preemption?
Key California appellate decisions addressing CUTSA preemption include K.C. Multimedia, Inc. v. Bank of America Technology & Operations, Inc. (2009) 171 Cal.App.4th 939, Silvaco Data Systems v. Intel Corp. (2010) 184 Cal.App.4th 210, and Angelica Textile Services, Inc. v. Park (2013) 220 Cal.App.4th 495. These cases establish that CUTSA displaces noncontract claims based on the same nucleus of facts as a trade secret misappropriation theory.
Does CUTSA preempt computer access claims under Penal Code section 502 or the CFAA?
It depends on the factual basis of the claim. If the computer access claim is based on the same alleged misuse of confidential information as the trade secret claim—rather than genuinely unauthorized access to a computer system—courts may sustain a demurrer on CUTSA preemption grounds. Courts distinguish between true unauthorized access (which may survive preemption) and authorized access followed by alleged misuse of information (which is more likely to be preempted).
