Patent Invalidation Search Services Backed by Defensible Prior Art
We help companies, legal teams, and decision-makers uncover prior art that can challenge patent claims, support opposition or reexamination, and strengthen litigation or licensing strategy.
What Is a Patent Invalidation Search?
A patent invalidation search identifies patent and non-patent prior art published before a patent’s priority date to determine whether issued claims can be challenged for lack of novelty or inventive step.
This service is commonly used when patent validity affects litigation, licensing, opposition, reexamination, or broader business strategy. If a blocking patent is creating risk, delay, or commercial pressure, a well-executed invalidation search can help you evaluate the strength of that patent with greater clarity.

- In-house IP teams assessing patent strength
