This ruling brings the total number of confirmed patent violations by Arista to five.
The patents relate to addressable memory and control plane policing, which are core technologies in network switching.
The USITC recommended a cease and desist order, as well as an import ban. On top of this, Arista must pay a five percent bond on covered products sold or imported during the review period.
In a blog post, Cisco general counsel and secretary Mark Chandler said: “We thank Administrative Law Judge Mary Joan McNamara and the USITC for their diligence and review of evidence that led to this decision.”
“Soon we expect the full rationale and background for the findings in the case to be published, and hope that Arista does not again attempt to shroud non-technical findings about its unlawful conduct from the public.”
He added: “Cisco’s goal remains to force Arista to cease the intentional and pervasive infringement that come from its ‘culture of copying’.”
