Texas Firm Sues Nintendo Over Chip Patent

A Texas company has sued Nintendo for alleged violations of a patent in making chips for use in its game consoles, Nintendo said on Friday.

Lonestar Inventions said in a June 7 complaint filed at a Texas district court that Nintendo's U.S. unit was infringing on one of its patents, the court's Web site showed.
The patent covers technology that boosts the performance of semiconductors.

Nintendo, maker of the popular Wii game console, is checking on the content of the suit, spokeman Ken Toyoda said.

Lonestar Inventions officials were not immediately available for comment.
