Invalidity Search
An invalidity search looks for prior art the examiner missed: documents published before the patent’s priority date that disclose, alone or in combination, what the granted claims cover. Law firms defending an infringement claim, in-house counsel preparing an inter partes review and brokers pricing a portfolio use it to challenge or value granted claims.
Who it is for: Law firms defending an infringement claim, in-house counsel facing an assertion or preparing an inter partes review, and brokers pricing a portfolio before acquisition.

Frequently asked questions
What is an invalidity search?
An invalidity search looks for prior art the examiner missed: documents published before the patent’s priority date that disclose, alone or in combination, what the granted claims cover. The result is used to challenge the claims in litigation, at the patent office, or in a licensing negotiation.
Where do you look beyond patent databases?
Non-patent literature is where most of the strong references are. We search journals, conference papers, theses and student projects, books, meeting minutes, standards contributions, product manuals and videos, as well as worldwide patent databases.
Why do you start with the prosecution history?
The file wrapper shows why the examiner allowed the claims and which arguments the applicant relied on. Knowing that focuses the search on the features that actually carried the patent to grant.
Can you also assess prior art we have already found?
Yes. We review existing references and charts against the claims and report where the mapping holds, where it is weak, and what is still missing.
