Case Overview
The Parties
⚖️ Plaintiff
Global semiconductor and consumer electronics leader with one of the world’s largest active patent portfolios, frequently asserting LED and semiconductor IP.
🛡️ Defendant
French technology and media services company. Named alongside TCP Lighting and Hawthorne Garden Company, representing a commercial lighting supply chain.
Patents at Issue
This case involved four U.S. patents covering semiconductor light-emitting device (LED) technology, specifically device architecture and manufacturing processes:
- • US7759140B2 — Light-emitting device and method of manufacturing the same
- • US9035341B2 — Manufacturing method of semiconductor light emitting device having sloped wiring unit
- • US9105762B2 — Semiconductor light emitting device and manufacturing method thereof
- • US9373746B2 — Semiconductor light emitting device with wiring unit arrangement

The Verdict & Legal Analysis
Outcome
The case terminated through a **stipulated dismissal under Federal Rule of Civil Procedure 41**, filed January 26, 2026. Samsung’s infringement claims were dismissed **with prejudice**, meaning Samsung cannot refile these specific claims against these defendants. Defendants’ counterclaims were dismissed **without prejudice**, preserving their ability to assert those positions in future. Each party bore its own costs.
Key Legal Issues
The consensual dismissal means no formal adjudication of patent validity, claim construction, or infringement occurred. The with-prejudice dismissal of Samsung’s claims signals a confidential settlement, a conclusion that continued litigation was commercially unjustifiable, or claim construction developments that weakened Samsung’s positions. The preservation of defendants’ counterclaims without prejudice retains strategic optionality for future disputes.
