Staples Inc.
In October 2009, Eolas sued a number of large corporations for infringement of the same patent. The 22 sued corporations include Adobe, Amazon.com, Apple, Argosy Publishing, Blockbuster, CDW Corp., Citigroup, eBay, Frito-Lay, The Go Daddy Group, Google, J.C. Penney Co. Inc., JPMorgan Chase &amp; Co., New Frontier Media Inc., Office Depot Inc., Perot Systems Corp., Playboy Enterprises International Inc., Rent-A-Center Inc., Staples Inc., Sun Microsystems Inc., Texas Instruments Inc., Yahoo!

As of June 2011, a number of these companies, including Texas Instruments, Oracle and JPMorgan Chase have signed licensing deals with Eolas, while others are still litigating.
