In May 2019, Palo Alto Networks filed a suit in the Northern District of California seeking declaratory judgments that it does not infringe five network traffic monitoring and packet processing patents held by Packet Intelligence LLC. July saw Packet Intelligence answer that complaint and file affirmative counterclaims, and now the NPE has sued Juniper Networks (3:19-cv-04741) in the same forum, alleging infringement of the same five patents, which were each also targeted with a July 2019 petition for inter partes review (IPR) by campaign defendant Nokia. Meanwhile, NetScout Systems has filed its opening brief in support of its Federal Circuit appeal from a jury verdict and final judgment in the Eastern District of Texas.

Late in 2017, Packet Intelligence LLC tried its overlapping claims of patent infringement against NetScout Systems (in October) and Sandvine (in November) to separate Eastern District of Texas juries, with contrasting results. The first jury found NetScout Systems to have willfully infringed multiple claims, also found not invalid, awarding Packet Intelligence $5.75M in damages, while the second jury found in Sandvine’s favor on infringement, awarding the NPE nothing. Neither case appears to have reached final resolution, with District Judge Rodney Gilstrap having ruled on some, but still in receipt of multiple other, post-trial motions. Meanwhile, Packet Intelligence has filed new lawsuits—asserting patents from the same network traffic monitoring and packet processing family—against Ericsson (2:18-cv-00381) and Nokia (2:18-cv-00382) in the same forum.
