The Verdict & Legal Analysis
Outcome
On **April 3, 2024**, the Court entered an order granting Push Data’s **Notice of Voluntary Dismissal Without Prejudice** as to all claims against Lane Bryant, Inc. The order specifically directed that each party shall bear its own costs, expenses, and attorneys’ fees. No damages were awarded, and no injunctive relief was granted or denied on the merits.
Legal Significance
The dismissal **without prejudice** is the single most legally significant procedural detail in this case. Unlike a dismissal with prejudice — which would bar re-filing — a without-prejudice dismissal preserves Push Data’s right to reassert these patents against Lane Bryant, or to pursue the same patents against different defendants, at a future date. The case terminated without any judicial determination of patent validity, infringement, or claim construction, meaning it carries no direct precedential value regarding the validity or infringement scope of the asserted patents.
