Corbin J. Cessna

Corbin J. Cessna is a patent litigator with experience representing both plaintiffs and defendants in high-stakes intellectual property disputes. His practice demonstrates a focus on patent litigation within the solar energy technology sector, particularly involving advanced solar cell structures and fabrication methods, such as TOPCon (Tunnel Oxide Passivated Contact) solar cell technology. Cessna’s case history shows an even split between plaintiff and defendant representations, indicating a versatile practice across both sides of patent infringement actions.

Throughout his career, Mr. Cessna has appeared for firms including Vinson & Elkins, White & Case, and PV Law in patent litigation matters. He was lead counsel for Maxeon Solar Pte. Ltd. in an infringement lawsuit against Canadian Solar, Inc., and represented Maxeon as an attorney in a similar action against REC Solar Holdings AS. The case against REC Solar Holdings AS was dismissed without prejudice in June 2025, suggesting a negotiated settlement or licensing agreement.

Cessna also has significant experience in Patent Trial and Appeal Board (PTAB) proceedings. He has represented clients in IPR proceedings, including for REC Solar Holdings AS in an IPR against Maxeon Solar Pte. Ltd. Additionally, in related litigation, the PTAB ruled in favor of Canadian Solar, Inc. in January 2026, invalidating certain Maxeon patents related to solar cell technology that were at issue in federal court. Maxeon subsequently appealed this PTAB decision to the Federal Circuit but voluntarily dismissed the appeal in July 2026.
