The lawsuit, filed Wednesday in a U.S. District Court in New York, alleges Pure Digital infringed on Advanced Video's patent for its Full Duplex Single Chip Video Codec. The technology is designed to compress the video and allow it to be displayed on small-screen devices.
Advanced is seeking unspecified damages and a "reasonable" royalty, according to a Reuters interview with Stephen Roth, attorney for Advanced Video. He noted Advance is not seeking to halt sales of the Flip Video cameras.
Pure Digital is aware of the lawsuit, a representative for the company said, adding: "The suit is without merit and we will defend it vigorously."
