Why should I file a provisional application for patent?

Provisional applications are less expensive and easier to file than non-provisional patent applications (NPAs). Provisional applications can be done quickly, in advance of an invention's public disclosure. This establishes an official invention date with the U.S. Patent Office.

Provisional applications offer a number of advantages, including immediate use of the label "patent pending." One of the most practical benefits of filing a provisional application is that it allows you time to assess your invention's potential before committing to the higher cost of filing an NPA. Provisional applications are not published by the Patent Office, giving you protection and privacy.

With a Provisional application on file, you can feel safe commercially promoting your invention with greater protection against theft. Finally, if you improve or change your invention after filing, the lower cost and turnaround time of a provisional application gives you the flexibility to file another application quickly and easily.
