In a significant power electronics patent infringement ruling, the U.S. Court of Appeals for the Federal Circuit affirmed a jury verdict of indirect and willful infringement against Vicor Corporation, upholding both enhanced damages and attorneys’ fees awards in favor of SynQor, Inc. Case No. 24-1879, closed February 13, 2026, following 625 days of appellate proceedings, delivers a clear message to the power conversion industry: aggressive defense strategies against well-documented infringement findings face an uphill battle at the Federal Circuit level.
The case centers on high-efficiency power converter technology — a commercially critical sector powering data centers, telecommunications infrastructure, and defense electronics. For patent attorneys, IP professionals, and R&D teams operating in this space, the court’s unequivocal affirmance of willfulness findings and downstream remedies provides important guidance on litigation strategy, enforcement posture, and the real financial consequences of continuing infringing conduct. This ruling reinforces the Federal Circuit’s consistent treatment of willful infringement as a threshold that, once crossed, opens defendants to substantial enhanced exposure.
Case Overview
The Parties
⚖️ Plaintiff
Massachusetts-based power electronics company with a robust IP portfolio focused on high-efficiency, unregulated bus converters and intermediate bus architecture (IBA) power systems.
🛡️ Defendant
Global technology conglomerate and major smartphone manufacturer competing in the premium device market with Galaxy series products.
The Patents at Issue
This landmark case involved six patents covering architectural and circuit-level innovations in high-efficiency power conversion, including unregulated and semi-regulated bus converter topologies used in IBA power delivery systems.
- • US7269034B2 — High-efficiency unregulated bus converter
- • US7564702B2 — The ‘702 patent central to the appellate verdict (Intermediate Bus Architecture)
- • US7072190B2 — Power conversion systems with improved efficiency
- • US7558083B2 — Unregulated bus converter with enhanced control
- • US8023290B2 — Distributed power system architecture
- • US7272021B2 — High-efficiency power converter circuit topology

The Verdict & Legal Analysis
Outcome
The Federal Circuit affirmed the jury’s verdict of indirect and willful infringement of U.S. Patent No. 7,564,702 (the ‘702 patent). Additionally, the court upheld both the district court’s enhanced damages order under 35 U.S.C. § 284 and the attorneys’ fees order under 35 U.S.C. § 285. The combined exposure of enhanced damages (potentially up to three times actual damages) plus attorneys’ fees represents one of the most severe remedy combinations available under U.S. patent law.
Key Legal Issues
The Federal Circuit’s unequivocal language — “we have considered Vicor’s remaining arguments and find them unpersuasive” — signals that Vicor mounted a broad-based challenge that failed to identify reversible error. Indirect infringement findings require proof of underlying direct infringement by a third party combined with either inducement or contributory infringement. Willful infringement, post-*Halo Electronics v. Pulse Electronics* (2016), requires subjective willfulness. The affirmance of enhanced damages (§ 284) indicates the district court’s determination was well-grounded, while attorneys’ fees (§ 285) for an “exceptional” case, as defined by *Octane Fitness v. ICON Health* (2014), were also properly affirmed.
