Invalidity opinions

Invalidity Opinions: Prior-art-based analysis to pressure test or challenge a patent's validity.

Not every asserted patent is valid. Hope IP conducts thorough prior art searches and prepares invalidity opinions when you're facing an infringement claim, evaluating a license demand, or considering a declaratory judgment action. The goal is straightforward: find documented evidence that the patent should never have issued in the first place.

Hope IP approaches invalidity work strategically. Sometimes an opinion provides leverage in settlement discussions. Other times, it supports a decision to challenge the patent through post-grant proceedings or litigation. The firm searches technical literature, prior patents, product documentation, and industry standards to uncover art that the examiner didn't see or didn't properly consider. The analysis addresses both anticipation and obviousness grounds, with a focus on building the strongest possible case for invalidity. You'll understand whether the patent is vulnerable, what the best invalidity arguments are, and how to use that analysis in your broader dispute strategy.
