US Ethernet Innovations (USEI) [NPE] filed three separate suits against Ricoh, Trendnet, and Xerox, alleging that the defendants’ fax machines, printers, print servers, cameras and copiers infringe three patents related to Ethernet technology.  USEI has filed four 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, and Toshiba, 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.  USEI is a direct extension of 3Com (since acquired by HP) and its website claims that USEI “was formed to continue 3Com Corporation’s successful licensing program on behalf of its portfolio of foundational patents in Ethernet technology.” USEI has reached license agreements with 30 companies including D-Link, Lucent Technologies (with subsidiaries Avaya and Agere), and Palm.  4/2, Eastern District of Texas, no judge yet assigned, 6:2012cv00235; 6:2012cv00236; 6:2012cv00237.
