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.
A provisional application for patent (provisional application) is a U.S. national application filed in the USPTO under 35 U.S.C. Â§111(b) . A provisional application is not required to have a formal patent claim or an oath or declaration.Provisional applications also should not include any information disclosure (prior art) statement since provisional applications are not examined. The benefits of the provisional application cannot be claimed if the 12 month deadline for filing a nonprovisional application has expired (unless the benefit of the provisional application has been restored under 37 CFR 1.78).
