Fallübersicht
Die Parteien
⚖️ Kläger (Berufungskläger)
Leading manufacturer of consumer electric hydrofoil boards, known for Waydoo Flyer and Flyer ONE products, and patent holder in eFoil technology.
🛡️ Beklagter (Berufungsbeklagter)
Manufacturer of competing eFoil products, involved in the underlying infringement dispute. Intellectual Property Insurance Services Corp. was also a co-defendant.
Streitige Patente
This appeal centered on two U.S. patents covering electric hydrofoil (eFoil) watercraft technology, reflecting the growing IP landscape in advanced personal watercraft. These patents were alleged to be infringed by MHL Custom’s competing products.
- • US9586659B2 (Application No. US15/064521): Electric hydrofoil board systems.
- • US9359044B2 (Application No. US14/509289): Related aspects of hydrofoil watercraft design and propulsion.

Das Urteil und die rechtliche Analyse
Ergebnis
The Federal Circuit granted Waydoo’s motion to dismiss its own appeal. Crucially, this was a procedural dismissal based on the non-finality of the lower court’s judgment, meaning no ruling on the merits of the patent infringement claims was issued. Each party was ordered to bear its own costs, and a previously imposed stay was lifted.
Wichtige rechtliche Fragen
The Federal Circuit’s reasoning hinged on the strict “finality doctrine” under 28 U.S.C. § 1295, which generally requires a final decision resolving all claims and parties before an appeal can be heard. The court determined the underlying judgment was non-final, thus preventing it from exercising appellate jurisdiction over the substantive infringement issues. This underscores the critical importance of appellate timing and the completeness of lower court judgments for patent litigants.

✅ Wichtigste Erkenntnisse
Federal Circuit jurisdiction requires a fully final judgment; multi-party cases with unresolved claims or parties create significant appellate timing risks.

Two U.S. patents: US9586659B2 (Application No. US15/064521) and US9359044B2 (Application No. US14/509289), both covering electric hydrofoil watercraft technology.
The court dismissed the appeal because the underlying judgment was non-final, meaning it did not resolve all claims and parties — a prerequisite for Federal Circuit appellate jurisdiction.
The substantive infringement claims remain unresolved. Both patents survive without invalidity findings, keeping enforcement risk elevated for competitors in the eFoil watercraft market.
