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.
