Invalidation/Validation Searches are exhaustive prior art search conducted after the grant of patent to either validate the enforce-ability of the granted claims made by a patent or to invalidate one or more claims of a competitor’s patent. The methods and resources adopted for Validity / Invalidity searches are same with the only difference being the results generated (valid or invalid patent claims). The invalidity/validity searches are extensive as they aim to probe into a large number of patents, patent applications, and all the non-patent documents available.
