Fanned Obvious

ABT sued Emerson Electric for infringing 5,547,017, which claimed fan operations for an air-conditioning system. A judge and jury found the patent infringed, and awarded royalties. On appeal, the CAFC reversed (2014-1618, 2014-1700), finding the patent obvious "as a matter of law" in light of four references which disclose four claimed features, but do not combine them as '017 did, or even suggest such a combination. Lacking evidence, the CAFC surmised "the motivation or rationale for combining those references can be found in the nature of the problem addressed, if not directly from the disclosures of the references themselves."
