InformationWeek reports (via 9 to 5 Mac) that Apple has filed a patent infringement lawsuit against an Anaheim, California company selling "knock-off" power adapters for Apple's MacBook and MacBook Pro models. Apple claims that the company sells third-party power adapters that infringe upon an Apple patent filed in 2001 and granted in 2003 for the design of Apple's laptop power supplies.

Apple's complaint charges that Media Solutions Holdings, through the Web sites www.laptopsforless.com, www.laptopacadapter.com and www.ereplacements.com, sells "various consumer electronic accessories at retail, including knock-off power adapters for use with genuine Apple portable computers."

"Through various Web sites and otherwise, the Defendants market these knock-off power adapters for use with Apple portable computers, such as the MacBook," the complaint states.

The power adapters apparently in question remain listed on the company's websites, but the specific product pages and ordering functionality appear to have been removed.
