Egenera alleged that Cisco's Unified Computing System (UCS) infringed on its U.S. Patent No. 7,231,430, which pertains to automated deployment of virtual processing networks. The appellate court affirmed the district court's decisions, including the summary judgment of noninfringement for claims 1 and 5, and the denial of Egenera's post-trial motions regarding claims 3 and 7. Key issues involved the construction of patent claim terms like "computer processor" and "emulate Ethernet functionality," and the sufficiency of evidence presented by Egenera to prove infringement.
