Cisco Wins Ruling in Patent Case Against Arista

Dow Jones News
Cisco Systems Inc. notched a victory on Tuesday in its legal
battle against rival Arista Networks Inc., winning a ruling from a
federal agency that could lead to a halt on imports of Arista's
networking hardware.
David Shaw, an administrative law judge for the International
Trade Commission, found that Arista infringed three Cisco patents
that cover software features used in the company's switching
systems. His ruling, called an initial determination, is a step
toward a possible ITC import exclusion order against Arista
products.
Such rulings are subject to a final determination by the
commission, a ruling Arista said it expects in June. Any exclusion
order may be blocked by the president or overruled by an appeals
court.
Still, the ruling is bad news for Arista, a fast-growing Silicon
Valley company founded in 2004 and led by former Cisco executives.
The company's stock fell 2.5% in after-hours trading following the
news.
Cisco, the biggest maker of networking gear, accused Arista of
violating its patents and copyrights in December 2014 in federal
court as well as at the ITC. Some of the allegations involve the
method used to type commands to program Cisco hardware -- known as
the command line interface, or CLI -- that is used by Arista and
some other competitors.
