Samsung has dropped another patent from its ongoing legal battle with Apple, reports “FOSS Patents” (http://macte.ch/vC0U8). The company has filed an unopposed motion to withdraw from the investigation all claims of U.S. Patent No. 6,897,843 on a “device and method for storing and reproducing digital audio data in a mobile terminal,” the article adds.

An International Trade Commission (ITC) hearing on Apple’s complaint against Samsung started on Thursday, May 31, and the ITC hearing on Samsung’s complaint against Apple will begin today. On Thursday, June 7, there will be two preliminary injunction hearings in the parties’ two federal lawsuits in the Northern District of California, notes “FOSS Patents.”

Apple and Samsung have filed more than 30 lawsuits against each other across four continents. For example, Apple alleges that Samsung copied the slide-to-unlock technology of its iPhone and iPad devices.
