- Free Expert Infringement Assessment
- In-Depth Identification of Non-Infringement Arguments
- USPTO-Registered Dual-Licensed Attorneys
- Improved Appeal Success Rate
Patent complaints on Amazon, Temu, SHEIN, or cease-and-desist letters from US rights holders often come with tight deadlines. foxSight's non-infringement opinion service helps you complete technical comparison, legal analysis, and defense materials within the critical window to maximize appeal and settlement success.
Our process typically begins with a free preliminary infringement assessment: analysts with product engineering backgrounds compare the asserted patent claims against your product structure and functional principles to identify risk and potential non-infringement arguments. Where a defense is viable, our USPTO-registered dual-licensed attorneys issue a formal Non-Infringement Opinion Letter — covering claim charts, doctrine of equivalents, prior art defenses, and more.
With 200+ US cross-border IP cases handled, we understand platform appeal rules, complainant strategies, and how US courts evaluate non-infringement defenses. We don't just deliver documents — we help refine appeal narratives, technical explanations, and evidence chains, and coordinate design-around or invalidity search when needed.
A rigorous non-infringement opinion demonstrates professionalism to platforms and counterparties alike, and forms a strong foundation for litigation or settlement. foxSight brings practical experience and fast response to help restore listings, unfreeze accounts, and reduce losses.
