Provisional Patent Application

A Provisional Patent Application is usually filed to establish a filing date (i.e. a priority filing date) for the patent application. A provisional application is valid for one year from the date of filing. A provisional application allows an inventor to mark his invention as "Patent Pending" and provides an opportunity for the inventor to work on the inventive concept and further crystallize it. A provisional patent application is usually followed up by filing a non-provisional patent application within one year from the date of filing the provisional patent application.

Non Provisional Patent Application

A provisional application can be converted to Non-Provisional Patent Application before the expiry of provisional application. A non-provisional patent application is granted as a patent if the inventive concept is found to be novel and non-obvious. A non-provisional patent application generally claims priority of a prior filed application.
