Text: Hayward next argues that even under the Board’s construction of “optimize energy consumption,” U.S. Patent Publication No. 2003/0196942 (“Jones”), Danfoss VLT 8000 AQUA Instruction Manual, April 16, 20014 (“Danfoss”), and Carrow meet that limitation. Each of those references discloses a closed-loop feedback system, which recognizes the flow rate and increases or decreases the motor speed to use the least energy possible to reach that flow rate. 1 As noted above, however, the “optimize energy consumption” claim limitation requires consideration of factors outside the universe of a closed-loop system. Because Jones, Danforth and Carrow do not disclose or teach systems with this additional capability, substantial evidence supports the Board’s decision. 1 Hayward does not argue on appeal that U.S. Pat. Pub. No. 2004/0117330 (“Ehlers”) discloses or teaches optimizing energy consumption under the Board’s construction. HAYWARD INDUSTRIES, INC. v. PENTAIR WATER POOL AND SPA 11
