Invalidity search is an exhaustive prior art search conducted after the issuance of a patent. The main purpose of the invalidity search is to validate the enforceability of a patent’s claims. Invalidation searches aim at finding documents that challenge the validity of a patent, where such documents were not found in the prior art search performed at the patent office during prosecution. Therefore, validity search is conducted to determine whether an issued patent is valid or not.

In a patent litigation case, one of the most important point to prove by the defendant is to find and properly apply the closest prior art.
