Cisco Systems Inc. has won a patent dispute case related to Wi-Fi technology, as a US appeals court cleared the networking equipment maker in a long-running battle against Commil USA.
The US Court of Appeals for the Federal Circuit on Monday reversed an earlier court ruling against Cisco that asked the tech giant to pay nearly US$64 million in damages to Commil, Reuters reported.
The appeals court determined that Cisco was not liable for directly infringing or inducing others to infringe a patent held by Commil on a way to help spread wireless signals over a large area, the report said.
Commil sued Cisco in 2007.
In 2011, a federal jury in Texas found that Cisco induced infringement by encouraging its customers to use Cisco products that infringe Commil’s patent.
The jury awarded Commil almost US$63.8 million in damages.
Two years later, the nation’s top appeals court ordered a new trial, saying that Cisco should have been able to mount a defense based on its “good faith belief” that Commil’s patent was invalid.
A three-judge Federal Circuit panel on Monday ruled in favor of Cisco.
