Mirror Worlds Sues Facebook, Adding Two Patents to Document Streaming Campaign

May 12, 2017

Publicly traded NPE Network-1 Technologies Inc., which reported multiple large settlements and a more than 74 percent increase in revenue last year, has filed its first new litigation in nearly 18 months. On May 9, its Mirror Worlds Technologies, LLC subsidiary sued Facebook (1:17-cv-03473), accusing the company of infringing three document streaming patents through provision of its Timeline and News Feed features. One of the patents-in-suit (6,006,227) has been previously asserted by Mirror Worlds in cases against Apple, Best Buy, Dell, HP, Lenovo, Microsoft, and Samsung that led to multi-million dollar settlements. The remaining two patents at issue, which are later issuing family members of the ‘227 patent (which expired in 2016), are new to litigation.
