The Verdict & Legal Analysis
Outcome
The Court granted the Joint Stipulation of Dismissal With Prejudice on July 14, 2025. All claims asserted by Secure Matrix LLC against Twin Liquors LP were dismissed without a damages award or injunctive relief.
Key Legal Issues
The infringement action was terminated through mutual agreement rather than adjudication, meaning no judicial finding was made regarding the validity or infringement of U.S. Patent No. 8,677,116 B1. The dismissal with prejudice legally bars Secure Matrix LLC from re-filing the same claims against Twin Liquors LP.
