CAFC finds critical appellant admission in Chevalier

The appellant to the CAFC lost in In re Chevalier.

Note the text

Our conclusion is strengthened by Chevalier’s admission that the deflectors of Kwak and Howk are “recognized equivalents performing the same function of converting axial flow to radial flow.” Appellant’s Br. 9. The Supreme Court stated in KSR that “when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” KSR, 550 U.S. at 416 (citing United States v. Adams, 383 U.S. 39, 50-51 (1966)). Here, the claimed invention merely substitutes the deflector of Howk, which is attached to the drive shaft, for the deflector of Kwak, which is attached to the floor of the basin. This substitution achieved only the predictable result of converting the axial flow of the gas-liquid mixture to radial flow.

Elsewhere in the decision:

This court reviews the Board’s determination of obviousness de novo and the Board’s factual findings for substantial evidence. Id. Substantial evidence is “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Consol. Edison Co. v. NLRB, 305 U.S. 197, 229 (1938). “[T]he possibility of drawing two inconsistent conclusions from the evidence does not prevent an administrative agency’s finding from being supported by substantial evidence.” Consolo v. Fed. Mar. Comm’n, 383 U.S. 607, 620 (1966).
