Cooper Notification , Inc. (“Cooper”) appeals from the summary judgment of the United States District Court for the District of Delaware holding that Twitter, Inc., Feder- al Signal, Inc., and Everbridge Corp. (collectively “the Defendants”) do not infringe claims 12 –18 of U.S. Patent 7,409,428 (the “’428 patent”). Cooper Notification, Inc. v. Twitter, Inc., 867 F. Supp. 2d 485 (D. Del. 2012). Because the district court did not err in granting summary jud g- ment of noninfringement, we affirm.
