The patent infringement lawsuit, filed in the Southern District Court of New York State, seeks reasonable royalties from Microsoft for not only infringing on I/P Engine’s patents in Microsoft’s own search engine, which employs filtering technology, but also for continuing to engage in the practice for years after alerted to the patents. I/P Engine alleges that Microsoft has been knowingly infringing upon U.S. Patent No. 6,314,420 (the ‘420 patent), which is titled “Collaborative/Adaptive Search Engine,” since at least October 2003 and U.S. Patent No. 6,775,664 (the ‘664 patent), which is titled “Information Filter System and Method for Integrated Content-Based and Collaborative/Adaptive Feedback Queries,” since at least December 2008.
