Earlier Filing Date of Provisional Precludes Patent Grant
In a July 7, 2010 ruling (In re Giacomini), the Court of Appeals for the Federal Circuit affirmed the Board of Patent Appeals and Interference’s rejection of U.S. Patent Application No. 09,725,737 (“the ’737 application”) pursuant to 35 U.S.C. § 102(e) as being anticipated by U.S. Patent No. 7,039,683 (“the ’683 patent”) which was issued to Vinh Tran. The ’737 application was filed on November 29, 2000 and was directed to a method of efficiently populating a cache with resources. The ’683 patent was filed on December 29, 2000 as a Non-Provisional Application, but claimed priority to a Provisional Application which was filed on September 25, 2000. Consequently, the filing date of the Provisional would make the ’683 patent prior art under 35 U.S.C. § 102(e) whereas the filing date of the Non-Provisional would not.
The Board determined, and the Applicants did not dispute, that the ’683 patent taught all of the claimed features of the ’737 application. Section 102(e) states that a person shall be entitled to a patent unless the invention was described in “(2) a patent granted on an application for patent by another filed in the United States before the invention by the applicant for patent” (emphasis added). Applicants argument was that since a Provisional Patent Application does not itself lead to the issuance of a patent, that its filing date cannot be used in formulating a rejection under 35 U.S.C. § 102(e). However, the Federal Circuit sided with the Board’s ruling and quoted 35 U.S.C. § 111(b)(8) , the pertinent part of which states that “[t]he provisions of this title relating to applications for patent shall apply to provisional applications for patent.”
The Federal Circuit clarified an important limitation in that the Provisional must have support for the invention disclosed and claimed in the Non-Provisional. Furthermore, since Applicants did not argue a lack of written description support before the Board, the argument was waived because Applicants failed to timely raise it below. The Federal Circuit’s ruling was also distinguished over In re Hilmer, which clarified that a U.S. Patent Application claiming priority to a foreign application has a priority date as of the filing date of the foreign application, but is only effective as 102(e) prior art as of its U.S. filing date. This difference arises from the wording of Section 102(e) wherein the application for patent must be “filed in the United States.” These subtle distinctions should be included among the considerations given precedence when determining whether to file first in the U.S. or abroad.
