Case Overview
The Parties
⚖️ Plaintiff
Non-practicing entity (NPE) patent assertion vehicle with a litigation-forward IP monetization strategy.
🛡️ Defendant
Global leader in embedded processing. Co-defendants NXP B.V. and NXP USA, Inc. were also named.
The Patent at Issue
This case involved a single U.S. Patent, covering technology in the semiconductor processing domain related to power management and multi-core processor operational logic.
- • US 8,549,339 — Power management and multi-core processor operational logic

The Verdict & Legal Analysis
Outcome
The case was resolved through a stipulated order of dismissal. Plaintiff Redstone Logics LLC’s claims were dismissed WITH prejudice, while Defendant NXP USA, Inc.’s counterclaims were dismissed WITHOUT prejudice. No damages amount was publicly disclosed.
Key Legal Issues
The asymmetric dismissal structure is legally significant. Dismissal with prejudice means Redstone Logics is permanently barred from re-asserting these claims against NXP. The dismissal without prejudice for NXP’s counterclaims preserves their ability to revive arguments if needed in the future. No formal adjudication on patent validity or claim construction was reached.
