Kansas Federal Court Applies “Selective Enforcement” Theory to Reject DTSA Claim

A Kansas federal court held that inconsistent enforcement of trade secret rights can defeat a claim under the Defend Trade Secrets Act (DTSA). In Edelman Financial Engines, LLC v. Mariner Wealth Advisors LLC, No. 2:23-cv-02515-HLT (D. Kan. June 5, 2026), the court applied a selective enforcement theory, holding that when a company does not consistently pursue legal remedies against similarly situated former employees, that inconsistency can be affirmative evidence that it failed to protect its trade secrets. While the selective enforcement theory has appeared in academic hypothetical discussions, the decision appears to be one of the clearest judicial applications of a “selective enforcement” theory in a trade secret case....

Representative Matters

  • Secured a significant victory (a preliminary injunction against patent infringement through trial) on behalf of Lonza Walkersville, Inc. against Israel-based Adva Biotechnology Ltd. in a case involving point-of-care cell-therapy technology.
  • Secured jury verdict, judgment and eight figure damages award following weeks’ long trial in Delaware Superior Court for c3.ai, a leading Enterprise AI software and application company, in novel matter alleging its former customer, diesel engine manufacturer Cummins Inc., misappropriated c3.ai's trade secrets and breached the parties’ contract by studying c3.ai's trade secrets and replicating them into Cummins' own application.
