Includes a patent infringement search. This search also includes patents that have expired. A right-to-use search combines an infringement search and a patentability search. The ultimate goal of a right-to-use search is as the name implies — the right to use the product or process. This includes determining the likelihood a new concept, process, device, etc. is patentable and attempting to uncover patents and patent application publications that may pose an infringement risk to a product. Preferably, the right-to-use search is performed before the release of the product.
