Narrative Opinion Summary
In this patent infringement case, MercExchange, L.L.C. accused eBay, Inc. and Half.com, Inc. of willful infringement of its patents related to online sale systems. The district court found infringement and awarded damages, but denied MercExchange's request for a permanent injunction and enhanced damages. On appeal, the court affirmed the infringement findings for the '265 patent but reversed the inducement finding against eBay for ReturnBuy's alleged infringement, citing insufficient evidence of intent. It also reversed the validity finding of the '176 patent for anticipation, directing a ruling in favor of Half.com. MercExchange's cross-appeal led to a remand for reconsideration of the '051 patent's invalidity for lack of enablement and the need for a permanent injunction. The appellate court upheld the denial of enhanced damages and attorney fees, determining no abuse of discretion occurred. The case was affirmed in part, reversed in part, vacated in part, and remanded for further proceedings.
