Intellectual Ventures I LLC et al v. Arista Networks, Inc.

Roughly one week ago, District Judge Patti B. Saris in Massachusetts granted three motions for summary judgment of noninfringement, brought by Dell (EMC), Lenovo, and NetApp. The ruling ended the claims as to the lone remaining patent in a case brought by Intellectual Ventures LLC (through subsidiaries Intellectual Ventures I LLC and Intellectual Ventures II LLC) (IV) in May 2016. A July 2019 suit in the same campaign remains active against Dell’s VMWare, and IV has now added to the campaign’s sprawl by accusing Arista Networks (6:20-cv-00749) of infringing three patents new to the litigation. IV targets Arista’s provision of its Extensible Operating System (EOS) and Containerized Extensible Operating System (cEOS), as well as certain routers and switches.
