NEW YORK (TheStreet) -- Cisco Systems (CSCO) shares are down 0.9% to $27.52 in trading on Friday after the networking based protocol device manufacturer sued rival Arista Networks (ANET) over claims that the company infringed on several of Cisco's patents.
"The heart of our action regards Arista's deliberate inclusion in its products of 12 discrete and important Cisco features covered by 14 different U.S. patents," said the company's general counsel in a statement today.

In response to the suit, Arista Networks released this statement, "We just became aware of the lawsuit and have not had an opportunity to evaluate the claims in detail. We will certainly be doing so in the coming days. While we have respect for Cisco as a fierce competitor and the dominant player in the market, we are disappointed that they have to resort to litigation rather than simply compete with us in products."
In separate Cisco litigation news, the U.S. Supreme Court said Friday that they will take up a case involving a federal appeals court decision to dismiss a $64 million jury verdict against the company for allegedly infringing on another rival's, Commil USA, patent for wireless technology. The case has been scheduled for March.
