Provisional and Non Provisional Patent Application

A provisional patent application is filed for establishing a filing date and expires after one year of its filing. A non provisional patent application establishes the filing date of the patent application and begins the examination process. The patent application will be examined by USPTO if it is a US application. The non provisional application is known as the utility patent application. Provisional application establishes a filing date and allows claiming the original application when you later file a non provisional patent application. A provisional patent application is inexpensive as compared to a non provisional patent application. The filing of provisional application was introduced in 1995 which offers inventors to file a lost cost utility application.

The major advantages of filing a Provisional Patent Application are:
•    For getting an earlier priority date
•    It is a simplified form of application as compared to non-provisional one.
•   The 12-month time period helps him in deciding whether he want to patent it or commercialize the   invention.
•    Similarly the 12-month time allows an inventor to further work on his invention.
•    Allows the inventor to use his invention with “Patent Pending” applied on it.
