Knock-Out Validity Search
A fast, focused assessment of the patent and non-patent material that could contest the validity of a subject patent’s claims.
The aim is to find prior art the examiner may have missed during prosecution — which is exactly what makes it useful in litigation and in licensing negotiations, where you need an early read before committing to a full study. If you need the complete version, see our patent invalidity search.
When Businesses Use a Knock-Out Search
Assessing or acquiring a patent portfolio
To assess a portfolio before acquiring it, and to understand what you would actually be buying.
Before launching a licensing campaign
To check the ground before a licensing campaign goes out, rather than after a target pushes back.
Filtering a multi-patent action
Where a patent owner intends to launch an action involving many patents, knock-out searches are run first to establish which of them will stand up.
When budget or time is short
When there is not enough time or budget for a complete validity search, a knock-out search gives you the essential answer quickly.
