Station Casinos Inc. is suing an Internet company based in Panama that it says is infringing on trademarks Station owns for three of its Las Vegas hotel-casinos. Station's suit says the defendants are operating sites on the Internet with domain names that include the phrases "boulderstation'," "sunsetstation" and "palacestation." The same defendants were sued by several MGM Mirage properties in the same court last year. MGM Mirage obtained an injunction and a $2.2 million judgment against them for infringing on the trademarks covering Bellagio, Circus Circus, Mandalay Bay, New York-New York and Treasure Island.
