AT&T warns Apple of video patent infringement

AT&T claims that Apple and others are infringing on its MPEG-4 video compression patents. Looking for global licensing agreements, AT&T has targeted Apple, CyberLink, DivX, InterVideo, and Sonic Solutions as companies whose products use the MPEG-4 technology. AT&T has also reportedly contacted national retailers that sell products from the companies, informing them that they may be held liable for infringement.

“With the recent explosion of products that use the MPEG-4 standard, including Apple’s video iPod and Creative’s Zen Vision:M, AT&T could stand to gather a financial windfall from its patented technology,” reports PC Magazine. “An increasing trend in mobile phone multimedia also signals potential future profits to be made through the global licensing program.”
