"Eolas Technologies, a company that ground through a years-long patent infringement lawsuit against Microsoft, now has sued a large swath of corporate powers for infringement of that same patent and another related patent concerning interactive programs on Web sites.
The list of defendants includes many high-profile companies inside and outside the tech world: Adobe Systems, Amazon, Apple, Blockbuster, Citigroup, eBay, Frito-Lay, Go Daddy, Google, J.C. Penney, JPMorgan Chase, Office Depot, Perot Systems, Playboy Enterprises, Staples, Sun Microsystems, Texas Instruments, Yahoo, and YouTube.
Eolas' suit is not to be taken lightly. Although the earlier Microsoft case took many years to resolve, and Eolas by no means won a complete victory, the patent involved did overall withstand heavy legal challenges despite many on the Web rallying to Microsoft's aid. Microsoft and Eolas won't describe terms of their 2007 settlement of the patent case"Update - apologies for losing the CNet link, hopefully now fixed.
