International License Exchange of America, LLC (ILEA) has filed suit against ADTRAN (1:17-cv-00562), its third complaint brought this month after cases against Ericsson (1:17-cv-00507) and NTT (1:17-cv-00508). The NPE’s latest lawsuit accuses ADTRAN of infringing six former Nortel patents (5,959,990; 6,970,461; 7,274,704; 7,277,533; 7,478,167; RE40,999), two of which (the ‘704 and 533 patents) are here asserted for the first time. The company is alleged to infringe through the provision of various Ethernet switches, routers, and gateways; IP phones; and line cards; as well as through certain cloud management services. Meanwhile, ILEA dismissed its case against Ericsson without prejudice on May 11; that complaint accused the company infringing the ‘990 and ‘999 patents through various types of enterprise networking hardware.

Equitable IP Corporation has initiated another litigation campaign, this one through Smart Semiconductor, LLC, a Delaware entity formed in July 2016. The NPE’s complaints assert three circuit operation patents (7,224,233; 7,242,254; 7,515,003), generally related to lock-in circuits for phase-locked loops, against Intel (1:17-cv-00457), Micron Technology (1:17-cv-00458), Toshiba (1:17-cv-00460), and Qualcomm (1:17-cv-00459). At issue are processors used within desktop and laptop computers (Intel) and within mobile devices (Qualcomm), as well as certain memory products (Micron, Toshiba). Smart Semiconductor acquired the patents, along with ten others, from the estate of the sole named inventor, Dr. Sangbeom Park, after his death.
