Chronologie du litige et historique de la procédure
| Date de dépôt | November 22, 2023 |
| Tribunal | Cour d'appel des États-Unis pour le circuit fédéral |
| Date de clôture | 1er mars 2024 |
| Durée | 100 days |
| Motifs de résiliation | Voluntary Dismissal (Fed. R. App. P. 42(b)) |
This appeal was filed in the District of Columbia circuit region, reaching the Federal Circuit — the exclusive appellate jurisdiction for U.S. patent cases. The 100-day duration from filing to dismissal is notably brief for Federal Circuit proceedings, which typically involve extensive briefing schedules. The rapid resolution strongly suggests settlement negotiations were underway.
Résultat
The Federal Circuit ordered the proceeding dismissed under Federal Rule of Appellate Procedure 42(b), based on the parties’ mutual agreement. The court further ordered that each side shall bear its own costs. No damages were awarded, and no injunctive relief was granted or denied on the merits. The case closed without any substantive ruling on the validity or infringement of the four asserted patents.
Signification juridique
The voluntary dismissal means no binding precedent was created by this Federal Circuit proceeding. For the broader patent litigation community, this is significant: the four patents-in-suit retain their presumption of validity under 35 U.S.C. § 282, and no appellate claim construction ruling constrains their future assertion or licensing. Rule 42(b) dismissals at the Federal Circuit are relatively uncommon at the appellate stage and typically reflect a negotiated resolution or a strategic decision that appellate risk outweighs the benefit of continued litigation.

Four U.S. patents: US10226376B2, US8287508B1, US10390989B2, and US10376407B2 — covering urinary management device technology.
The dismissal was voluntary under Fed. R. App. P. 42(b) by mutual agreement of both parties, with each side bearing its own costs. No merits ruling was issued.
The four asserted patents remain valid and uninterpreted by appellate claim construction, preserving Sage Products’ future assertion options while leaving Purewick without a binding invalidity or non-infringement ruling in its favor.
