File Provisional Patent Applications: Ins and Outs


If you are, in the future, thinking to file provisional patent applications then this article is for you!

According to the U.S. trademark and patent office (USPTO), a provisional application is a legal document filed in the USPTO, that establishes an early filing date but does not mature into an issued patent unless you file a regular non-provisional patent application within one year.

A Provisional Patent Application is not examined and so you can also avoid the costs associated with non-provisional patent prosecution for a year while determining whether your invention is commercially viable or not. If yes, then you can perfect your invention in that extended time.

However, the one year, beginning from the date when you file provisional patent application, cannot be extended and so you must file a non-provisional during the specified 1-year period to benefit from the PPA.

Notwithstanding the specified period, you may still benefit from the PPA by filing a grantable petition in case if you file your non-provisional patent application after 12 months (1 year) but within 14 months. The petition should include the reason for the ‘unintentional’ delay and the required petition fee.
