CRUZ, Intellectual Property Attorney, DLA Piper US LLP, U.S.A.  \nABSTRACT  \nIn the United States, provisional patent applications can provide an additional year of patent protection, for a total of 21 years from the initial filing date. With such an extension, a provisional application provides parity with foreign applicants who, pursuant to the Paris Convention, may file for a U.S. patent within 12 months of the foreign filing. Provisional applications have both advantages and disadvantages, so proper management is essential. The advantages include the preservation of a priority date immediately after an invention is conceived, a one-year delay for further developing the invention, an extra year of patent protection, and constructive reduction to practice of the invention. In addition, provisional applications provide an inexpensive way to avoid possible statutory barsand preserve absolute novelty for foreign filing purposes. They also enable the use of the phrase “Patent Pending” to mark products embodying the invention. The disadvantages include a possible increased overall cost of obtaining a patent, potential loss of trade secrets, and a false sense of security. An inventor must also file a nonprovisional application within one year, and the subject matter of anonprovisional application is limited to subject matter in the provisional application.  \n1. INTRODuCTION  \nBeginning in 1995, inventors were able to file provisional patent applications in the United States. This informal type of patent application establishes a priority filing date and provides inventors one additional year to prepare and file a formal utility patent application.  \nProvisional patent applications were established in the United States to place domestic inventors on an equal footing with foreign inventors. Before the advent ofU.S. provisional applications, foreign (Paris Convention signatory) applicants could claim the benefit of a foreign priority date, yet have their U.S. patent term measured from a later U.S. filing date. Foreign inventors were thus granted a term of patent protection that could last for 21 years. U.S. applicants, on the other hand, were disadvantaged: their patent term was measured from their initial U.S. filing date and limited to 20 years. Effective June 8, 1995, domestic applicants were given the opportunity to file provisional applications, thereby establishing U.S. priority dates that would not count against any resulting U.S. patent term. Allowing for U.S. patent protection that lasts 21 years from an initial filing date, this change in policy established parity between U.S. and foreign inventors.  \nAs an informal application, a provisional patent application does not require all the formal elements of a utility patent application. For example, provisional applications are not required to include formal claims, a declaration of inventorship, or drawings, all of which are required for utility applications. Instead, all that is required is a written description of an invention and a coversheet that, among other things, identifies the document as a provisional patent application.  \nCruz RL. 2007.
