And Speaking of Prior Art . . . Harrah's Entertainment, Inc. (NYSE: HET) said it plans to appeal a recent decision by the United States District Court for the District of Nevada granting a Station Casinos, Inc. motion for summary judgment in patent litigation between the two companies. In granting Station's motion, the District Court last month ruled that Harrah's Customer Recognition Patents and a portion of the 013 Patent are invalid. The District Court denied other motions by Station seeking to invalidate and render unenforceable the patents. The District Court has additional motions pending with respect to the portion of Harrah's 013 Patent claims that are not affected by the invalidity ruling. Harrah's will dismiss the unaffected 013 Patent claims, and will not pursue those claims against Station.
