Utility Patents

UTILITY PATENTS

There are two types of utility patent applications: provisional and nonprovisional. A provisional application is a quick and inexpensive way for inventors to establish a U.S. filing date for their invention, which can be claimed in a later-filed nonprovisional application. A provisional application is automatically abandoned 12 months after its filing date and is not examined. An applicant who decides to initially file a provisional application must file a corresponding nonprovisional application during the 12-month pendency period of the provisional application in order to benefit from the earlier provisional application filing. A nonprovisional application is examined by a patent examiner and may be issued as a patent if all the requirements for patentability are met. Each year the USPTO receives more than 500,000 patent applications. Most of the applications filed with the USPTO are nonprovisional applications for utility patents.
