Arista Networks climbed more than 7% despite the company's loss in a court ruling over a patent dispute against Cisco Systems ( CSCO 1.69% ). Cisco had alleged that Arista had violated Cisco's patents, and a judge at the International Trade Commission found in favor of Cisco on two of the five patents at issue in the case. Yet even with the adverse ruling potentially leading to a negative adjudication expected within the next four months or so, Arista investors seemed confident that the company could find a way to get around any intellectual property issues and release new software that will avoid any controversy going forward. In particular, Arista has done a good job of assuring customers that there won't be any disruption in their services regardless of the eventual outcome of the case, and investors have faith that the company therefore won't see a big drop in revenue as a result.
