Co., Ltd., Case No. 2016-1729. Samsung appealed from the United States District Court for the Eastern District of Texas. The panel affirmed the district court's claim construction and denial of Samsung's motions for judgment as a matter of law (JMOL) on obviousness and damages, but vacated and remanded the district court's denial of Samsung's motion to limit damages.

Rembrandt Wireless sued Samsung for infringement of U.S. Patent No. 8,023,580 (the '580 patent) and U.S. Patent No. 8,457,228, which include claims directed to “a system and method of communication in which multiple modulation methods are used to facilitate communication among a plurality of modems in a network.” Slip Op. at 3 (quoting the '580 patent). The jury found in favor of Rembrandt on infringement and validity. Samsung filed post-trial JMOLs on obviousness and damages, which were denied, as was Samsung's pre-trial motion to limit damages. Samsung appealed the district court's: 1) claim construction; 2) denial of Samsung's JMOL on obviousness; 3) denial of Samsung's JMOL on damages; and 4) denial of Samsung's motion to limit damages.
