Apple filed the lawsuit against Media Solutions Holdings in the California Central District Court on Monday, according to InformationWeek. Apple claims the power adapters violate a patent the company holds on the design of its own adapters.
The power adapters in question come with Apple's MacBook and MacBook Pro line of notebooks. Apple also sells the adapters separately for $79 from its online and retail stores.
