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’”.
