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.

For the second half of March, RPX saw 19 transfers of patents recorded with the USPTO.
