Ninth Circuit Affirms Dismissal and Fee Award in Semas v. Chemetall Trademark Case

WISECODE Take

In September 2026, the U.S. Court of Appeals for the Ninth Circuit ruled on Semas v. Chemetall US, Inc. (No. 24-6584), upholding the dismissal of a trademark infringement suit brought by Metalast Inc. and David Semas. Many business owners mistakenly believe that changing venues or defendants provides a second chance, but this case proves that improper litigation tactics backfire. The court applied the doctrine of res judicata to bar the claims and affirmed an award of attorney fees against the plaintiff and his counsel due to forum shopping and unprofessional conduct. This judgment sets a clear strategic boundary: refiling settled trademark disputes in different jurisdictions leads to penal financial losses. For cross-border businesses, using litigation as a harassment tool without solid substantive grounds carries high risks. Companies pursuing standard trademark protection remain unaffected. To manage international trademark legal status and risk, Knowledge Dictionary provides trademark monitoring services to assess litigation feasibility. When facing foreign trademark disputes, companies should: First, thoroughly review prior litigation history and the scope of res judicata before filing overseas; Second, focus strategy on proving new infringing facts rather than seeking venue arbitrage. Litigation is a strategic tool, not an endless war of attrition; respecting judicial boundaries is key to safeguarding financial resources and reputation.
