INTRODUCTION  \n¶1 In 1994, Congress enacted the Uruguay Round Agreements Act (URAA)1 in an effort to bring the United States into conformance with international patent standards and \"place domestic applicants on an equal footing with foreign applicants . \"2 The URAA introduced substantial changes in U.S. patent law. One of the most signiﬁcant changes was the amendment of 35 U.S.C.A. § 111 (West 1994) to allow inventors (both domestic and foreign) to ﬁle a special application: the provisional patent application .3  \n¶2 In the years following ratiﬁcation of the URAA, much has been written about the various nuances and intricacies of ﬁling provisional patent applications in the United States . In the midst of this voluminous discourse, it has been difﬁcult for the conscientious practitioner to determine exactly what to say to a client who asks, \"Should I ﬁle a provisional application?\" The purpose of this Note is to provide a quick and practical guide to the beneﬁts and shortcomings of ﬁling provisional patent applications, including the use of provisional applications as part of an overall patent ﬁling strategy. Part II will provide a brief overview of provisional applications and how they differ from non-provisional applications. Part III will evaluate the beneﬁts of ﬁling provisional applications. Part IV will discuss the disadvantages, including potential pitfalls for the unwary. Finally, some general conclusions will be drawn in Part V regarding the use of provisional applications .  \nII. PROVISIONAL PATENT APPLICATIONS  \n¶3 The purpose behind the creation of the provisional application was to eliminate a disparity ineffective patent terms between domestic and foreign inventors ﬁling for patents in the United States.4 Under the Paris Convention, the United States is required to grant inventors a patent term of twenty years, running from the date of their U.S. ﬁling.5 The Paris Convention further dictates that foreign inventors have up to one year, following their ﬁrst foreign ﬁling, to ﬁle for a patent in the United States .6 Thus, domestic inventors ﬁling in the United States are disadvantaged because foreign applicants can effectively obtain twenty-one years of patent protection, measured from their ﬁrst foreign ﬁling date, while domestic inventors are limited to twenty years. The provisional application introduced by the URAA seeks to eliminate the disadvantage faced by domestic inventors .7  \n¶4 The URAA allows inventors to take advantage of an earlier ﬁling date through a provisional application without having to ﬁle a complete patent application for a period of up to twelve months.8 According to this new scheme, certain aspects of the patent, such as priority,9 prior art, 10 and  \nstatutory bars, 11 will be measured from the date of the provisional application . However, the clock on the twenty-year patent term will not start running until the non-provisional application is ﬁled. Therefore, provisional applicants have up to one \"free\" year to develop, use, and market their products without diminishing their twenty-year patent term. This effectively gives domestic inventors an opportunity to obtain twenty-one years of U.S. patent protection, thus putting them on par with foreign applicants .  \n¶5 Provisional applications are different from non-provisional applications in several important ways. Non-provisional applications must satisfy the requirements of 35 U.S.C.A. § 112, ﬁrst paragraph 12 (written description of invention), § 112, second paragraph13 (carefully drafted claims), and § 11314 (relevant drawings) . Applications must also be accompanied by a sworn oath from each applicant, attesting to his or her st","cbCaipJeajEGMXGf","https://ap.wps.com/l/cbCaipJeajEGMXGf","pdf",258426,"English","# I.
