Network-1 Technologies, Inc. said its subsidiary Mirror Worlds Technologies, LLC initiated patent litigation against Facebook, Inc in the US District Court for the Southern District of New York for alleged infringement of three patents.
“The lawsuit alleges that the patents in suit are infringed by the core technologies that enable both Facebook’s Newsfeed, which according to Time Magazine is the ‘epicenter of its success’ and Facebook’s Timeline features,” said Network-1 Technologies.
“The lawsuit further alleges that Facebook’s unauthorized use of the stream-based solutions of the patents in suit has helped Facebook become the most popular social networking site in the world with more than 1.94 billion monthly active users as of March 2017.
“The patents in suit are among the patents acquired by Network-1, through MWT, from Mirror Worlds, LLC on May 21, 2013 and relate to computer systems using stream-based solutions.
“The inventions described in the patents in suit resulted from the work done by Yale University computer scientist, Professor David Gelernter, his then graduate student, Dr. Eric Freeman, and their co-inventors in the mid-1990s.”
Network-1 said that since its acquisition of the Mirror Worlds patent portfolio in May 2013, it had achieved licensing revenue and other revenue of about $47 million which included, among other things, license agreements with Apple and Microsoft.
