For applications filed on or after June 8, 1995, Section 532(a)(1) of the Uruguay Round Agreements Act (Pub. L. 103-465, 108 Stat. 4809 (1994)) amended 35 U.S.C. 154 to provide that the term of a patent (other than a design patent) begins on the date the patent issues and ends on the date that is twenty years from the date on which the application for the patent was filed in the United States or, if the application contains a specific reference to an earlier filed application or applications under 35 U.S.C. 120, 121, or 365(c), twenty years from the filing date of the earliest of such application(s). This patent term provision is referred to as the \"twenty-year term.\" Design patents have a term of fourteen years from the date of patent grant. See 35 U.S.C 173 and MPEP § 1505.
All patents (other than design patents) that were in force on June 8, 1995, or that issued on an application that was filed before June 8, 1995, have a term that is the greater of the \"twenty-year term\" or seventeen years from the patent grant. See 35 U.S.C. 154(c). A patent granted on an international application filed before June 8, 1995, and which entered the national stage under 35 U.S.C. 371 before, on or after June 8, 1995, will have a term that is the greater of seventeen years from the date of grant or twenty years from the international filing date or any earlier filing date relied upon under 35 U.S.C. 120, 121 or 365(c). The terms of these patents are subject to reduction by any applicable terminal disclaimers (discussed below).

Term of patent in the United States
In the United States, under current patent law, the term of patent, provided that maintenance fees are paid on time, are:
For applications filed on or after June 8, 1995,[1] the patent term is 20 years from the filing date of the earliest U.S. application to which priority is claimed (excluding provisional applications).[2]
For applications that were pending on and for patents that were still in force on June 8, 1995, the patent term is either 17 years from the issue date or 20 years from the filing date of the earliest U.S. application to which priority is claimed (excluding provisional applications), the longer term applying.[3]
The patent term in the United States was changed in 1995 to bring U.S. patent law into conformity with the World Trade Organization\'s Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs) as negotiated in the Uruguay Round. As a side effect, it is no longer possible to maintain submarine patents in the U.S., since the patent term now depends on the priority date, not the issue date.
Design patents, unlike utility patents, have a term of 14 years from the date of issue.[4] |
