A provisional application for patent lasts 12 months from its filing date. The USPTO will not grant extensions for any reason. The inventor(s) must file a Non-Provisional Patent Application within that period to take advantage of the Provisional Application for Patent's filing date.
Anything that is not included in the provisional patent application is not considered to be a part of your invention. For this reason you may hear patent attorneys explain that a provisional patent application is helpful to protect whatever is included in the application (as I said above).herefore, an applicant who files a provisional patent application must file a corresponding non-provisional application for patent (i.e., âregular patent applicationâ) during the 12-month pendency period of the provisional application in order to benefit from the earlier filing of the provisional application.
