What are the advantages of filing a provisional patent application?

Filing a provisional patent application offers several advantages, as outlined in the MPEP:

1. Establishing Priority: It allows applicants to quickly and inexpensively file provisional applications and establish a priority date for their invention.
2. Paris Convention Priority: It starts the Paris Convention priority year, allowing foreign filings within 12 months while maintaining the U.S. filing date.
3. Simplified Filing: As stated in the MPEP, No claim is required in a provisional application and No oath or declaration is required in a provisional application.
4. Patent Term: The MPEP notes, The domestic priority period will not count in the measurement of the 20-year patent term. This puts domestic applicants… on equal footing with foreign applicants with respect to the patent term.
5. Time for Development: It provides a 12-month period to further develop the invention before filing a nonprovisional application.

These advantages make provisional applications a useful tool for inventors to secure an early filing date while allowing time for further development and market assessment.
