Search Error! Federal Circuit Invalidates Vringo Search Engine Patents

On August 15, the Federal Circuit, in a nonprecedential opinion, reversed a lower court ruling, denying I/P Engine, Inc., a subsidiary of Vringo, Inc., a $30 million patent infringement jury verdict by invalidating two of its internet search engine patents. I/P Engine brought suit against AOL Inc., Google, Inc., and others in the Eastern District of Virginia for allegedly infringing its patents, U.S. Patent Nos. 6,314,420 and 6,775,664, which relate to systems and methods for filtering internet search results, using both content-based and collaborative filtering. In November 2012, the district court found I/P Engine’s patents valid and that defendants infringed those patents. The jury awarded I/P Engine over $30 million in damages and a 3.5% running royalty.
