Commstech LLC has added HP Enterprise (HPE) (6:19-cv-00462) as a defendant in its sole litigation campaign to date, which has already seen cases filed this summer against Cisco (in May) and Allied Telesis and Juniper Networks (in July). The patents asserted in the campaign, including the three now in suit against HPE, are generally directed to network traffic management and memory management. At issue again is a long list of HPE networking products and software that incorporate the RFC 4607 specification “related to ‘Source-Specific Multicast for IP’” and/or that “operate with the ArubaOS-Switch software support ‘Quality of Service (QoS) prioritization’”.
Texas NPE Commstech LLC has followed up its Western District of Texas case against Cisco, filed in May 2019, with two July suits, one each against Allied Telesis (3:19-cv-04006), filed in the Northern District of California, and Juniper Networks (4:19-cv-00545), filed in the Eastern District of Texas. Three of the six patents asserted against Cisco, generally related to network traffic management and memory management, are at issue in the new complaints, with infringement allegations targeting networking products and related software. On July 26, Cisco filed an answer to the complaint against it.
Commstech LLC, a Texas entity under the management of Hao Ni of Ni, Wang and Massand PLLC, received a portfolio of nine US patents from Harris Corporation last fall. The NPE has now asserted six of those patents in a new Western District of Texas suit against Cisco (6:19-cv-00296). The patents generally relate to network traffic management and memory management, with infringement allegations focused on Cisco’s provision of router operating systems, certain network devices running them, and related products.
