Are You Making Use of the Benefits Offered by the Provisional Applications?
Often overlooked by non-U.S. applicants, the provisional application is available to effectively extend patent term while securing an early filing date.
The U.S. Patent & Trademark Office (“USPTO”) permits the filing of “provisional” applications. A provisional application is different from a regular application in that it is not examined and therefore cannot directly issue as a patent. Instead, the provisional application secures a filing date from which priority may be claimed in later-filed regular U.S. or non-U.S. patent applications. The formatting flexibility and potential procedural benefits provided by a provisional application make it a useful tool that should be considered by non-U.S. applicants and practitioners.
The format requirements for a provisional application are minimal, and therefore the form of a provisional application is quite flexible. To be accepted by the USPTO, a complete provisional application must include a cover sheet (which identifies the application as a provisional application, provides the names and addresses of the inventors, and provides the title of the application), a written description, and drawings (if necessary). No background, summary, abstract, or claims are required. Accordingly, almost any type of information, including lab notebooks, raw data, and design drawings, may be submitted as a provisional application. It is recommended, however, to include a specification that is similar to a regular U.S. application to ensure that it adequately supports the claims submitted in a later-filed application, thereby validating your right to claim priority to the provisional application filing date. A provisional application is not entitled to claim priority to any other application, and therefore must be the first-filed application.
The primary procedural benefit afforded by a provisional application is preserving an early filing date without reducing the term of any patents issuing from later-filed applications that claim priority to the provisional application. When a provisional application is filed, the USPTO will issue a filing receipt which identifies a filing date. The applicant has one year from the provisional application filing date in which to file a regular U.S. application and any non-U.S. applications that may claim priority to the provisional application. Consequently, references cited in the later-filed applications must pre-date the provisional application filing date. Significantly, however, the term of a patent issuing from the later-filed regular U.S. or non-U.S. applications is measured from the filing date of the later-filed application, and not the provisional application. Accordingly, the provisional application process can be used to secure an early filing date while effectively extending patent term.
