Texas-based NPE Consolidated Work Station Computing, LLC (CWSC) has filed two lawsuits in a single week, suing Haivision (1:15-cv-08936) and Check Point Software Technologies (1:15-cv-09140) for infringement of a single patent (6,823,475). CWSC has now filed six suits in 2015 alone, and these two new filings continue its escalation of a campaign that began in 2010 but has become much more active this year. The ‘475 patent relates to a computer motherboard with multiple redundant power supplies, and it has been the sole patent-in-suit for every case in the campaign. Like CWSC’s previous suits, the accused products are both types of server hardware.

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).
