Peter Joseph Giacomini, Walter Michael Pitio, Hector Francisco Rodriguez, and Donald David Shugard (collectively, “Giacomini”) appeal from a decision of the Board of Patent Appeals and Interferences (“Board”) rejecting certain claims of U.S. Patent Application No. 09/725,737 as anticipated under 35 U.S.C. § 102. Ex parte Giacomini, No. 2009-0139,
I.
Giacomini’s application — “Method and Apparatus for Economical Cache Population” — was filed on November 29, 2000. The application claims a technique for selectively storing electronic data in a readily accessible memory called a “cache.” When a system retrieves requested data from a source, it. stores the data in its cache so that it can retrieve the data more quickly next time. Because the cache has a limited space, the system must selectively store data. Giacomini’s technique populates the cache with data only when the system receives a certain number of requests for that data. Claim 1 is representative:
A method comprising:
populating a cache with a resource only when at least i requests for said resource have been received;
wherein i is an integer and is at least occasionally greater than one.
This cache does not normally include infrequently requested data because it “at least occasionally” stores data for which multiple requests have been made. Claims 1, 2, 8, 11, 12, 15, 22-24, 27, 28, 31, and 32 of Giacomini’s application are at issue on appeal.
II.
The Board rejected certain claims of Giacomini’s application as anticipated under 35 U.S.C. § 102 by the Tran patent, and, in the alternative, by U.S. Patent No. 6,463,509 (“the Teoman patent”).
The Tran patent — “Electronic Information Caching” — describes a caching technique based on an anticipated demand for data. Its “anticipating module” considers “past requests for access to the same or related electronic information by access requesters.” Tran patent col.1 ll.49-52. Such “past requests for information may be measured by the frequency or volume of access requests.” Id. col.3 ll.25-28. The Board found, and Giacomini does not dispute, that the Tran patent teaches all of the claimed features in Giacomini’s application.
The central issue at the Board was the eligibility of the Tran patent to serve as prior art under 35 U.S.C. § 102(e). The Tran patent’s filing date is December 29, 2000, exactly a month after Giacomini filed his application. However, the Tran patent claims priority to a provisional application (“the Tran provisional”) filed on September 25, 2000, which antedates Giacomini’s filing date. Therefore, the Board held that the Tran patent has a patent-defeating effect as of the filing date of the Tran provisional.
Giacomini appeals the Board’s decision that the Tran patent and the Teoman patent each anticipates his application. This court has jurisdiction under 28 U.S.C. § 1295(a)(4).
III.
This court reviews the Board’s legal conclusions, including statutory interpretation, without deference. In re Swanson,
IV.
Section 102 governs the conditions of patentability. The statute, in pertinent part, states:
[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....
35 U.S.C. § 102(e)(2) (emphasis added). An application that a patent was “granted on” is the first U.S. application to disclose the invention claimed in the patent. In re Klesper,
As noted, Giacomini does not dispute that the Tran patent describes the invention claimed in Giacomini’s application. Also, the Tran provisional, which antedates Giacomini’s filing date, was the first U.S. application to describe the invention. The Board found that “[t]he Provisional Application No. 60/234,996, from which Tran claims priority under 35 U.S.C. § 119(e), discloses that ‘[a]nticipating requests for electronic information ... is generally performed based on one ore [sic] more criteria, e.g., past requests for information.’ ” Ex parte Giacomini, No. 2009-0139, at *5. Section 119(e) treats a nonprovisional application as though filed on the date of its corresponding provisional application. 35 U.S.C. § 119 (Benefit of earlier filing date; right of priority) recites:
(e)(1) An application for patent filed under section 111(a) or section 363 of this title for an invention disclosed in the manner provided by the first paragraph of section 112 of this title in a provisional application filed under section 111(b) of this title, by an inventor or inventors named in the provisional application, shall have the same effect, as to such invention, as though filed on the date of the provisional application filed under section 111(b) of this title, if the application for patent filed under section 111(a) or section 363 of this title is filed not later than 12 months after the date on which the provisional application was filed and if it contains or is amended to contain a specific reference to the provisional application....
35 U.S.C. § 119(e)(1) (emphases added).
An important limitation is that the provisional application must provide written description support for the claimed invention. Because Giacomini never argued before the Board that the Tran provisional failed to provide written description support for the claimed subject matter in accordance with section 119(e), Giacomini waived the argument by failing to raise it below. See In re Watts,
This conclusion is consistent with “[t]he fundamental rule ... that the patentee must be the first inventor.” Alexander Milburn Co. v. Davis-Bournonville Co.,
Giacomini argues that 35 U.S.C. § 119(e) shifts a patent’s priority date but not its effective reference date to the filing date of an earlier provisional application. In other words, Giacomini contends that although the Tran patent claims the benefit of priority to the Tran provisional, the Tran patent does not have a patent-defeating effect as of the Tran provisional’s filing date.
Giacomini’s distinction between priority date and effective reference date largely stems from In re Hilmer,
But at the time this court’s predecessor decided Hilmer, section 119 only governed the benefit of claiming priority to an earlier filing date in foreign countries. Id. at 862. Congress added section 119(e) along with the enactment of provisional applications in 1994. See Uruguay Round Agreements Act, Pub.L. 103-465, 108 Stat. 4809 (1994). Therefore, broad language in Hilmer concerning section 119 is not applicable to provisional applications. Also, Giacomini misses an important distinction between Hilmer and the present
Section 102(e) codified the “history of treating the disclosure of a U.S. patent as prior art as of the filing date of the earliest U.S. application to which the patent is entitled, provided the disclosure was contained in substance in the said earliest application.” Id. (emphasis added). According to Hilmer, an earlier foreign application does not shift a corresponding patent’s effective reference date because section 102(e) explicitly requires the earlier application to be “filed in the United States.” Hilmer,
Accordingly, the Tran patent has a patent-defeating effect as of the filing date of the Tran provisional, or September 25, 2000. Giacomini did not file his application until months after Tran filed his provisional application. Giacomini is not the first to invent in the United States and thus is not entitled to a patent. Because this court affirms the Board’s finding of anticipation based on the Tran patent, this court will not review the Board’s finding with respect to the Teoman patent.
V.
Because the Board correctly rejected Giacomini’s application under 35 U.S.C. § 102(e) on the basis that the invention was described in a patent claiming priority to a U.S. provisional application filed before Giacomini’s filing date, this court affirms.
AFFIRMED.
