U.S. patent law[]
A nonprovisional patent application is an application for patent filed under 35 U.S.C. §111(a) that includes all patent applications (i.e., utility, design, plant, and reissue) except provisional applications. The nonprovisional application establishes the filing date and initiates the examination process. A nonprovisional utility patent application must include a specification, including a claim or claims; drawings, when necessary; an oath or declaration; and the prescribed filing fee.
