The Verdict & Legal Analysis
Outcome
On **March 6, 2024**, Judge Mazzant entered an order dismissing all claims asserted by Push Data LLC against Zumiez, Inc. **with prejudice** following Push Data’s filing of a Notice of Voluntary Dismissal. The order specified no right of appeal and that each party would **bear its own costs, expenses, and attorneys’ fees**. No damages were awarded, and no injunctive relief was issued, terminating the case entirely on procedural grounds.
Legal Significance
The dismissal with prejudice is legally significant, barring Push Data from reasserting the same claims against Zumiez on the same patents. This suggests a negotiated resolution rather than a unilateral retreat. The mutual agreement on costs also indicates a consensual exit, effectively neutralizing any possibility of fee-shifting under 35 U.S.C. § 285. No claim construction, invalidity, or infringement findings were issued, meaning the patents remain in force and could be asserted against other defendants.
