In re Herman MIHALICH.

No. 92-1125.

United States Court of Appeals, Federal Circuit.

Oct. 20, 1992.

Before NIES, Chief Judge, BENNETT, Senior Circuit Judge, and RADER, Circuit Judge.

RADER, Circuit Judge.

DECISION

In an August 21, 1991, decision and an October 30, 1991, reconsideration decision, the Board of Patent Appeals and Interferences rejected claims 1-6, 8, 9 and 10 of Patent Application Serial No. 07/303,937. Mr. Herman Mihalich, the applicant, appealed all the rejections except claims 5 and 6. Because the record does not support the Board's finding of anticipation, this court reverses the Board's rejection of claims 1 and 8.

OPINION

Mr. Mihalich's patent application claims several variations of a "portable beverage dispenser capable of use as an integrated unit both in the home and for outdoor events without electrical power facilities." Patent Application Serial No. 07/303,937. Briefly, the application describes a thermally insulated cabinet with two compartments. The lower compartment holds a beverage container, generally a beer keg. The upper compartment is an ice chest with a cooling coil leading from the beverage container. In operation, gas pressure forces beverage from the container in the lower compartment through the cooling coil in the upper ice chest. Thus, the invention dispenses chilled beverage without an electrical refrigeration unit.

Central to the patentability of Mr. Mihalich's invention is the partition between the dispenser's two compartments. Mr. Mihalich designed the partition to permit the ice in the upper chamber to cool the beverage container in the lower chamber, thus allegedly solving a problem with prior beverage dispensers. Before Mr. Mihalich's invention the act of drawing warm beer through a cooling coil caused formation of an excessively foamy beer. The sudden drop in temperature made what Mr. Mihalich's application calls "picnic beer."

Mr. Mihalich's invention purports to solve the foamy beer problem with a partition between the upper and lower chambers of his dispenser composed of "thermally conducting material." Id. This partition facilitates a "thermal interchange" between the cooling (upper) and storage (lower) chambers. Id. The thermal interchange cools the beverage in the lower compartment. This temperature drop prevents the sudden cooling reaction that occurs when warm beverage is drawn into the cooling coil. In sum, Mr. Mihalich claims a beverage dispenser which solves the "picnic beer" problem without electricity.

The Board sustained the rejection of claims 1 and 8 under 35 U.S.C. § 102(b) (1988). The Board sustained the rejection of claims 2, 3, 4, 9, and 10 under 35 U.S.C. § 103 (1988). The Board sustained the rejections of claims 5 and 6 under the second paragraph of 35 U.S.C. § 112 (1988). Mr. Mihalich did not appeal the rejection of claims 5 and 6.

This court reviews anticipation, a question of fact, under the clearly erroneous standard of review. In re King, 801 F.2d 1324, 1326, 231 USPQ 136, 138 (Fed.Cir.1986). To anticipate a claim, a prior art reference must, either expressly or inherently, disclose each and every limitation in the claim. Verdegaal Bros. v. Union Oil Co., 814 F.2d 628, 631, 2 USPQ2d 1051, 1053 (Fed.Cir.), cert. denied, 484 U.S. 827 (1987).

The examiner asserted, and the Board concurred, that United States Pat. No. 4,225,059 ('059 or Kappos) anticipated Mr. Mihalich's application. Kappos also discloses a beverage cooler and dispenser. Both Kappos's and Mihalich's inventions feature a dual chamber beverage dispenser. Kappos, however, describes the upper chamber of the beverage dispenser as "insulated." Kappos actually claims "an insulated ice chamber in the upper interior portion of said container defining a compartment in the lower portion thereof." Kappos, col. 2, lines 58-60. Further the '059 patent describes: "An insulated ice tray or chamber 20 is provided in the top interior of container 10 and communicates with the lower main compartment 22." Id. at col. 1, lines 60-62.

Thus, Kappos does not expressly disclose the "thermally conducting" partition element in claims 1 and 8 of Mr. Mihalich's application. While the upper and lower compartments of Kappos "communicate" via the connecting cooling coil and dispensing means, Kappos makes no reference to thermal interchange between the compartments. The Board clearly erred in finding that the structure described in Kappos inherently discloses a "thermally conducting" partition.

Despite Kappos's unambiguous reference to an "insulated" ice compartment, the examiner determined that the '059 patent describes insulation only in the upper and side walls of the ice chamber. The examiner found that the bottom of the Kappos's ice tray, unlike the side walls, is not insulated. The drawings accompanying the '059 patent, however, use identical markings for the side walls and the compartment bottom. Fig. 3, '059.

Relying in part on the Manual of Patent Examining Procedure (MPEP) section 608.02 (8th Rev. May 1988), the Board found that only the upper wall of the Kappos ice tray was insulated. The Board interpreted Kappos's drawings to show diagonal cross-hatching, the symbol for metal, for the side and bottom walls.

The Kappos drawings are, at best, inconclusive. First, the markings in Fig. 3 of Kappos are horizontal cross-hatchings, not diagonal, as shown in MPEP section 608.02. Second, in Fig. 4 of the Kappos patent, the side walls of the ice tray do not show cross-hatching, but bear no markings whatsoever. Third, the Kappos specification refers to "[a]n insulated ice tray or chamber 20." Kappos, col. 1, line 60. Yet the number 20 in Fig. 3 points to a horizontally cross-hatched side wall of the ice tray. The inconsistencies in the Kappos drawings betray the Board's finding that the '059 patent inherently disclosed the "thermally conducting material" in Mr. Mihalich's partition between the dual chambers. Rather, Kappos unambiguously refers to an "insulated" ice tray. Because Mr. Mihalich claims a partition of "thermally conducting material," Kappos cannot anticipate claims 1 and 8.

In claim 1, Mr. Mihalich further specified that the thermal interchange between the upper and lower compartments would be "effective" to cool the beverage and prevent the "picnic beer" foaming reaction. The Kappos patent did not address, let alone purport to solve, the "picnic beer" problem. Because metals have widely varying thermal conductivities, the mere assertion that Kappos' ice tray bottom is metal does not necessitate a conclusion that Kappos inherently discloses sufficient thermal interchange to prevent picnic beer.
