Services > Validity/Invalidity

Picture
A validity/invalidity search attempts to locate prior art that calls into question the validity of an issued patent's claims. The validity search is often conducted prior to acquisitions or licensing negotiations to assist in evaluating the validity, strength and ultimate value of a single patent or portfolio of patents. An invalidity search is typically conducted in response to litigation, be it threatened or initiated. No matter the catalyst, a successful validity/invalidity search requires an exhaustive search for prior art, either singular or in combination, that predates the patent in question. 

The "Scorched Earth" prior art search leaves no stone unturned when locating critical prior art. Reviewing material unavailable electronically and accessing individuals and professional networks, the "Scorched Earth" search can be highly effective.
