What is a Patent Invalidity Search?
An analysis for understanding the strength of patent claims. A patent invalidity (or patent validity) search can be used to determine the viability of an invalidity defense when facing a patent infringement suit. Invalidity prior art searches are used to invalidate a patent that has been or may be asserted. It also may also be used to pro-actively assess the validity of a patent prior to enforcing it.
