An analysis of the patent and the 20+ companies which could be affected is covered on PatentMonkey. Interestingly, Yahoo sued Google back in 2004 with a patent Yahoo obtained when they acquired Overture. The net result was Yahoo owning 5% of Google. Perhaps Yahoo will use the patent to take a 5% stake in all the MashUps knowing some will pay off handomsly."
