US Ethernet Innovations (USEI) [NPE] filed suit against Digi International, Epson America, and NetSilicon, alleging that the defendants’ printers and system-on-chip products infringe three patents related to Ethernet technology.  USEI has filed nine prior suits since October 2009 against over 35 defendants, including Acer, Apple, ASUS, AT&T, Barnes & Noble, Canon, Dell, Fujitsu, Gateway, HP, Intel, Marvell, NVIDIA, Sony, Texas Instruments, Toshiba, Trendnet, and Xerox, and has been subject to three actions for declaratory judgment.  The patents-in-suit originated with 3Com and were assigned to USEI in October 2009.  According to the USEI website, the entity “was formed to continue 3Com Corporation’s successful licensing program on behalf of its portfolio of foundational patents in Ethernet technology.”  HP acquired 3Com in 2009.  5/25, Eastern District of Texas, no judge yet assigned, 6:2012cv00351.
