A Provisional Patent Application is a temporary application filed in the US patent office that is valid for only year after filing. The advantage of a provisional patent application is that it is much less costly than a non-provisional application, since it does not require any patent claims. Provisional patent applications also do not require a very detailed description of the invention, and only a few clear illustrations depicting the invention can be enough.
Provisional patent application provides a patent pending status right after it is filed.
A provisional patent application is recommended when
· there is an Urgency;
· a commercial disclosure;
· submission of paper or a thesis;
· inventors leaving the company;
· an accidental disclosure, and
· there are many competitors.
