After quickly settling its first patent infringement suit, filed against Sprint earlier this year, Ohio-based Small Cell Innovations LLC has added a second case to its only litigation campaign to date. The complaint accuses Verizon (Cellco) (1:15-cv-08378) of infringing a single patent (7,990,912) through its Verizon Network Extender product (a device designed to allow calls from indoor locations where outdoor cellular coverage does not reach). The ‘912 patent issued to Go2Call.com, Inc. (acquired by deltathree in 2007) in August 2011 and concerns a femtocell that provides voice connectivity to mobile devices over a radio network. RPX reviewed the patent in an OMA in October 2014 (Go2Call Base Station-OMA).
