Case Overview
The Parties
⚖️ Plaintiff
A global leader in display technology, particularly in advanced OLED panels for smartphones, TVs, and other devices.
🛡️ Defendant
A rapidly growing Chinese display manufacturer and formidable competitor to Samsung, especially in the OLED market.
Patents at Issue
The lawsuit involved five U.S. patents, all critical to OLED display technology:
- • US11594578B2 — Organic light emitting device pixel circuit and driving method therefor.
- • US7414599B2 — Pixel arrangement structure for organic light emitting display device.
- • US9818803B2 — Stage circuit and organic light emitting display using the same.
- • US10854683B2 — Organic light emitting device pixel circuit and driving method therefor.
- • US9330593B2 — Organic light emitting device pixel circuit and driving method therefor.

The Verdict & Legal Analysis
Outcome
The case was voluntarily dismissed without prejudice pursuant to Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure. This means Samsung Display retains the right to refile the same claims against BOE Technology in the future. There was no public declaration of damages, injunctive relief, or a finding of infringement or invalidity.
Key Legal Issues
The voluntary dismissal without prejudice is a highly strategic move. It is not a judgment on the merits but a procedural election by the plaintiff. This avoids a potentially adverse claim construction (Markman) ruling that could have defined key patent terms in a way detrimental to Samsung's infringement theories or BOE's invalidity defenses.
