On February 4, 2015 Barnes & Noble, Inc. filed a motion asserting that our cause of action on the ‘336 patent was barred by the Kessler doctrine because of the ITC’s finding of non-infringement. A hearing was held on March 17, 2015 in the U.S. District Court for the Northern District of California regarding the matter. A ruling is expected shortly.

On April 10, 2015 multiple defendants in the District Court action filed a motion arguing for invalidity of the ‘749 patent. The court has scheduled a hearing for May 19, 2015 in regards to this matter.
