The Verdict & Legal Analysis
Outcome
Encryptawave Technologies filed a Notice of Voluntary Dismissal with Prejudice pursuant to Fed. R. Civ. P. 41(a)(1), terminating the action against OnePlus. The dismissal was entered with each party bearing its own costs, expenses, and attorneys’ fees — a standard provision signaling no monetary settlement was publicly disclosed. No damages award, injunctive relief, or claim construction ruling was issued.
Procedural Significance of Rule 41(a)(1)
The mechanism of dismissal carries strategic weight. Under Rule 41(a)(1), a plaintiff may voluntarily dismiss without a court order only before the defendant has served an answer or a motion for summary judgment. The “with prejudice” designation means Encryptawave cannot refile this specific action against OnePlus on the same claims.
