1it enterpriseThe second significanttriumph the Cisco has registered against Arista in their ongoing legal conflict since it began in 2014 as the US Judge ruled today that Arista Networks trespassed on two Cisco switch patents. The case will now be reviewed by the International Trade Commission (ITC) as Judge MaryJoan McNamara has issued an initial determination on the case. Arista’s switches could once again be banned from import into the US should the ITC find against Arista. Earlier this year ITC has ruled against the Arista and the company was bannedfrom importing its products into the US market regarding another part of the case. However, in the month of November the company has announced the United States Customs has allowed them to start the import of its networking gear in the United States.

The new product from the company with redesigned software Extensible Operating System is not within the possibility of the limited rejection order issued by the United States International Trade Commission in Investigation No. 337-TA-944 and therefore may be imported into the United States. Cisco reported that this time the ruling judge found the following:

  • Violation of U.S. Patent 6,377,577 (“Access Control List Processing In Hardware”)
  • Violation of U.S. Patent 7,224,668 (“Control Plane Security and Traffic Flow Management”)

These are required to improve the process of networking products, and to guard the control plane of a switch or router.
