Another day, another lawsuit. Apple is suing companies it said are selling unauthorized electronic accessories such as chargers, speakers and cables for the iPod, iPhone and iPad, reports "Bloomberg Businessweek" (http://macosg.me/2/lw).

“Many are of inferior quality and reliability, raising significant concerns over compatibility with and damage to Apple’s products,” Apple said in the complaint, citing a user comment that a charger from one of the companies drained his iPod rather than replenishing the battery.

In the complaint, Apple said the unauthorized products are infringing as many as 10 patents and violating its trademarks. The complaint, filed July 22 in federal court in San Francisco, identifies six sellers based in California and one in Washington and said Apple could name as many as 20 additional companies, notes "Bloomberg."
