What is a Provisional Patent?
A provisional application for patent is a U.S. patent application for patent filed in the United States Patent Office (USPTO). A provisional patent application allows filing without a formal patent claim, formal drawings, an oath or declaration, or any information disclosure (prior art) statement. In addition, the provisional patent is not examined by the USPTO but allows the term “Patent Pending” to be applied in connection with the description of the invention.
A provisional application provides a lower-cost first patent filing of your invention in the United States.
A provisional application for patent (provisional application) lasts for 12 months from the date the provisional application is filed. The 12-month period cannot be extended. Therefore, an applicant who files a provisional application must file a corresponding non-provisional (regular) application for patent during the 12-month period in order to benefit from the earlier filing of the provisional application. If not, the provisional application is abandoned.
