In this patent infringement case, Plantronics, Inc.

On March 23, 2012, the district court granted-in-part Aliph’s motion for summary judgment of noninfringement and invalidity, construing certain disputed terms, finding in relevant part that the accused products do not infringe claims 1 and 10, and holding the asserted claims invalid as obvious.
