A validity patent search will determine whether a patent will withstand attack in litigation. A validity search report validity /invalidity search provides all relevant prior art that are not cited by the examiner, yet potentially reads on the claims and valid enough to challenge the issued patent, which may be used to prove the validity/invalidity search validity or lack thereof of a patent already obtained.
Also, a validity patent search determines how useful the patent is in licensing negotiations. A prospective licensee may want to conduct a validity patent search to determine the strength of the patent. Upon receiving the results, the licensee can then adjust its minimum royalty payments according to the findings before entering into the license agreement.
The search team together with the client requirement, study the subject patent to frame the key features and search strategies to find the patent references.

Invalidation search is mainly used by company/patent attorney to invalidate an in-force patent, thereby allowing the company to practice that technology without paying the royalty and can be used to negotiate licensing fee against the in-force patent.

The Grounds to Invalidate a Patent Based on Prior Art
The grounds to invalidate a patent differ according to the national patent laws of different countries. However, most national laws recognize grounds such as publication of the invention prior to the priority date of the application for patent, sales of the invention, prior public knowledge, or prior public use. An exhaustive prior art search will be directed at each of these separate sources of prior art.
