The Verdict & Legal Analysis
Outcome
On July 9, 2024, Chief Judge Roy K. Altman entered an order dismissing the action without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), following the plaintiffs’ filing of a Notice of Voluntary Dismissal (ECF No. 17). The court ordered that each party bear its own attorneys’ fees and costs.
No damages were awarded. No injunctive relief was issued. The case produced no ruling on the merits of the infringement claim or the validity of U.S. Patent No. 11,857,482 B1.
Key Legal Issues
The dismissal was entered under Rule 41(a)(1)(A)(i), which permits a plaintiff to voluntarily dismiss an action without a court order before the opposing party serves an answer or a motion for summary judgment. Because no defense counsel appeared and no responsive pleading was filed, this procedural mechanism was available as of right.
The “without prejudice” designation is legally significant. It preserves Hyperice’s right to refile the same infringement claims in the future — against this defendant or related entities — without being barred by res judicata. This is a standard and strategically deliberate choice when plaintiffs resolve enforcement actions through negotiated compliance or marketplace takedowns rather than final judgment.

U.S. Patent No. 11,857,482 B1 (Application No. US17/681367), covering battery-powered percussive massage device technology associated with the Hypervolt product line.
