The Patent Office has no role in the commercialization of patent. However, for a nominal fee-currently $25 for each published item-the USPTO will publish an announcement of patents and serial numbers available for license or sale. This publication occurs on the second Tuesday of each month in the Official Gazette for Patents. Similarly, the World Intellectual Property Organization (WIPO) maintains a register in which applicants can offer to license their inventions disclosed in international applications. Applicants may request that the WIPO International Bureau post indications of availability of patents for licensing purposes on its free PATENTSCOPE service. These resources help the inventor connect with potential manufacturers or licensees.
