Interference No. 103,303 evaluation as to what weight the evidence, if it is relied upon by us, should be accorded. INTERFERENCE-IN-FACT We hold that an interference-in-fact exists. The interference having been declared under 35 U.S.C. § 135(a), it is presumed that an interference-in-fact exists and that each party's claims designated as corresponding to a count define the same patentable invention as the count. An "interference-in-fact" exists when at least one claim of a party that is designated to correspond to a count and at least one claim of an opponent that is designated to correspond to the count define the same patentable invention. 37 CFR § 1.601(j). The party filing a preliminary motion urging that an interference-in-fact does not exist has the burden of proof on the motion. Kubota v. Shiyuba, 999 F.2d 517, 27 USPQ2d 1418 (Fed. Cir. 1993). The party must show that its claims corresponding to the count are directed to a separate patentable invention from each of its opponent's claims designated in the notice as corresponding to the count.
