Apple on Thursday sued three US resellers for allegedly infringing on the patents behind the MagSafe power adapters for the MacBook and MacBook Pro. The Northern District of California complaint accuses Brilliant Store, Hootoo and Sunvalleytek International of selling copies such as the "AC Adapter MagSafe" without permission. The companies involved in some cases have made it clear both that they sell the actual power bricks as well as the duplicates.
