Kenyon obtained a voluntary dismissal for Sony Electronics Inc. of a patent infringement suit filed against it by Illinois Computer Research, LLC. ICR had alleged that Sony infringed several claims of US Patent No. 7,111,252. According to ICR's complaint, the patented invention allows reviewing of excerpts from a digital book for preview prior to purchase, but prevents the reader from obtaining and reviewing the entire book prior to purchase. With a motion by Sony for summary judgment of non-infringement pending, ICR dismissed its claims against Sony with prejudice. Case number 1:08-cv-7322 (2009).
