Spherix Inc. on Thursday said that it is suing Cisco Inc.,
alleging that $43 billion in Cisco sales infringed on Spherix
patents.
Spherix--which described itself as an "intellectual property
development company committed to the fostering and monetization of
intellectual property" -- said Cisco infringes on 11 patents it
acquired in December.
The patents, Spherix said, were developed by inventors at Nortel
Networks, which filed for bankruptcy protection in 2009 and
subsequently sold off its patent portfolio and operations.
"The company believes that the vast majority of Cisco's
switching and routing revenue from March 2008 through the present
has been generated by products and services implementing technology
that the company believes infringes on the 11 patents," Spherix
said.
Cisco representatives didn't immediately respond to a request
for comment.
