Case Overview
The Parties
⚖️ Plaintiff
Singapore-headquartered premium solar technology company known for high-efficiency solar cell designs and an extensive IP portfolio.
🛡️ Defendant
Norwegian solar energy company with global manufacturing, producing N-type monocrystalline silicon cells (N-Peak product line).
Patents at Issue
This case involved three U.S. patents covering advanced solar cell technology that formed the basis of Maxeon’s infringement claims:
- • US8222516B2 — covering foundational solar cell structure technology
- • US8878053B2 — directed at solar cell fabrication and interconnection methods
- • US11251315B2 — a more recent patent covering advanced photovoltaic cell configurations

The Verdict & Legal Analysis
Outcome
On June 25, 2025, Judge Gilstrap granted the Joint Motion to Dismiss (Dkt. No. 46), ordering that all claims, defenses, and counterclaims asserted in the case be dismissed without prejudice. No damages were awarded, and no injunctive relief was issued, signaling a likely negotiated resolution between the parties.
Key Legal Issues
The “without prejudice” designation is legally significant: it preserves Maxeon’s right to re-file infringement claims on the same patents against REC Solar in the future. Joint motions of this nature in patent litigation almost universally reflect a negotiated license agreement, a cross-licensing arrangement, or a covenant not to sue.
