InterTrust on Tuesday said it has received a new patent that it will use against Microsoft in a closely watched intellectual property dispute that could affect the way consumers access music and other digital content. InterTrust, which makes digital rights management software designed to help copyright owners control distribution of their material, was awarded a new patent on a method of transferring digital content between computing devices. The company said it plans to add the patent claim to a suit it filed against Microsoft in April. In that suit, InterTrust claims Microsoft violated its patents by including anti-copying technology similar to InterTrust's in its software for storing and playing music and video files on a personal computer.
