SURVEILLANCE PATENT OWNERS LOSE BID TO NIX GOVERNMENT'S INVALIDITY DEFENSE

摘要

The U.S. government has persuaded a federal judge to let its invalidity defense go forward against claims that the Department of Homeland Security and several security companies with government contracts are infringing patents covering surveillance technology. U.S. District Judge Charles F. Lettow of the Court of Federal Claims on January 13 denied a summary judgment motion filed by plaintiffs 3rd Eye Surveillance LLC and Discovery Patents LLC, which contended the defense was untimely.
