Advantages of filing a provisional utility patent application versus a non-provisional utility patent application: 1. It allows filing without a formal patent claim, an oath or declaration, or any information disclosure (prior art) statement. 2. The government filing fee is $130 (Small Entity) versus $800 (Small Entity) for a non-provisional (complete) patent application. 3. It provides the means to establish an early effective filing date in a later-filed non-provisional patent application. Specifically, Applicants are entitled to claim the benefit of a provisional application in a corresponding non-provisional application filed not later than 12 months after the provisional application filing date. 4. It also allows the term "Patent Pending" to be applied in connection with the invention. 5. The resulting publication of the non-provisional patent application or issued patent would be treated as a prior art reference under 35 U.S.C. §102(e) as of the earlier provisional application filing date. 6. The twenty (20) year patent term is measured from the filing date of the later filed non-provisional application thus providing an additional one (1) year of protection.
