Earlier in April, one of the two cases in PacSec3, LLC’s networking campaign, filed last October against F5 Networks, was dismissed with prejudice. A few weeks later, the Texas NPE has now filed a second wave of suits, accusing Cisco (6:21-cv-00388), Juniper Networks (6:21-cv-00387), McAfee (2:21-cv-00140), and Palo Alto Networks (2:21-cv-00141) of infringing the same three patents through the provision of features within their respective firewall systems designed to prevent packet flood attacks. The cases join another October 2020 suit, against NetScout Systems, now entering claim construction before District Judge Alan D. Albright in the Western District of Texas.

Recently formed Texas NPE PacSec3, LLC has kicked off its first litigation campaign, suing F5 Networks (2:20-cv-00697) in the District of Utah and Netscout Systems (6:20-cv-00914) in the Western District of Texas. Three patents generally related to a firewall system for managing packet transmission are asserted in each new complaint, with PacSec3 targeting the provision of firewalls, more particularly network traffic management features within the Arbor Peakflow SP and BIG-IP Application Security Manager (ASM), respectively. PacSec3 is the second NPE associated with Dynamic IP Deals, LLC (d/b/a DynaIP) president Carlos Gorrichategui to launch litigation over the past few months.
