Accordingly, Xing purports to provide “a system and method for reducing the fuel consumption of a work vehicle that takes into account the operating efficiencies of the engine, transmission and various other power consuming components of the vehicle.” Id. at 1:63–67.
Patent 9,975,538 B2 Based on the arguments presented and the cited references, we find Petitioner’s unopposed definition of the level of ordinary skill reasonable, supported by the prior art evidence, the Specification, and Dr. Stein’s Declaration testimony (Ex. 1003 ¶¶ 21–24), and, for purposes of this Decision, adopt it as our own.
More particularly, Petitioner asserts that “Willis’s milling machine, modified to include Xing’s algorithm and CVT, would have resulted in a controller that adjusted engine speed based on load and predefined efficiency points, as claimed.” Id. at 47 (citing Ex. 1006, 2:9–12, 3:50–67, 11:65–12:11).
Relying on the declaration testimony of Dr. Stein, Petitioner asserts that one of ordinary skill in the art “would have been motivated to modify Willis to include a variable transmission and control system like that taught by Xing to ‘maintain a desired rotor speed.’” Id. at 51 (citing Ex. 1003 ¶¶ 85–87).
Reply 20–21)), Patent Owner argues Petitioner’s argument is unpersuasive based on the deposition testimony of Dr. Kemal, who “testified that, even in view of Petitioner’s hypothetical configuration in which the swash plate angle is at zero, power could still be transmitted from the engine to the rotor.” Id. at 18–19 (citing Pet.
