Arista Networks, Inc. (NYSE: ANET), commonly "Arista," is a public networking equipment and software company headquartered in Santa Clara, California. It was founded in 2004 by Andreas Bechtolsheim, David Cheriton, and Kenneth Duda (originally named Arastra, Inc.), and has been publicly traded since its June 2014 IPO. Per its FY2024 Form 10-K, Arista employed about 4,412 people and reported roughly $7.0 billion in revenue for the year ended December 31, 2024; Market capitalization has been reported in the hundreds of billions of dollars, though the figure moves with the stock. CEOs: Jayshree Ullal.
Arista designs and sells high-speed Ethernet switching and routing platforms for data center, cloud, AI, campus, and enterprise networks. Its core platform is the Extensible Operating System (EOS), a Linux-based network operating system, paired with CloudVision network-management software and R-series, X-series, and Etherlink switching/routing hardware built on merchant silicon. Revenue is predominantly product sales (~84% in FY2024) with the remainder from support services. Major end customers include Microsoft and Meta Platforms, each over 10% of revenue.
Patent-litigation posture: Arista is an operating company, not an NPE. Its tracked appearances are four plaintiff-side PTAB petitions and one district court case as defendant — the plaintiff petitions are defensive IPR challenges to patents asserted against it, not offensive assertions. It is best characterized as a defending operating company that counterattacks in the IPR forum.
Notable cases: The cluster centers on Corrigent Corporation v. Arista Networks, Inc. (D. Del., filed April 2022), in which Corrigent asserted U.S. Patent Nos. 6,957,369 ("Hidden failure detection") and 7,593,400, targeting Arista's switching products. Corrigent filed parallel suits against Dell and Cisco. Arista's 2023 IPR petitions against Corrigent patents (e.g., IPR2023-00515 on the '431 patent) were joined with Cisco's and Dell's, and the parties litigated claim construction in Delaware in 2024. The venue is the District of Delaware, a common forum for patent suits, not the Eastern District of Texas.
Some Corrigent corporate-history details in the pleadings (founding year, Nasdaq listing) come from party filings and could not be independently verified here.
