RPX took note, among the USPTO assignment records made available during the first half of March, of the transfer of one set of patents to Fortress Investment Group LLC, after the NPE assignor’s default on a prior financing agreement. Fortress intervened in the campaign asserting some of those patents, bringing the litigation to a relatively rapid close. RPX also took notice of the transfer of patents from multiple assignors to another entity, Knapp Investment Company Limited, a British Virgin Islands entity that has never filed suit. The records made available in early March also contain transfers to frequent plaintiffs, including affiliates of patent monetization firms IP Valuation Partners LLC and Monument Patent Holdings, LLC, as well as Blackbird Tech LLC and Empire IP LLC.

Dynamic Hosting Company LLC (DHC) has added 23 new defendants to its campaign, including Amazon, Apple, ASUS, BlackBerry, HTC, Huawei, LG Electronics, Microsoft, Pantech, Samsung, Sharp, Sony, T-Mobile, Verizon (Cellco), and ZTE. DHC’s complaints target defendants’ mobile phones with a visual voicemail application that connects over cellular networks. The NPE alleges that the phones infringe two patents related to fax-over-IP (FoIP) with time-based polling (5,826,026, 6,216,156).

Dynamic Hosting Company LLC (DHC) filed its first round of litigation, naming 11 defendants: Brother International, Canon, Eastman Kodak, Epson, Google, Hewlett-Packard, Konica Minolta, Lantronix, Oki Data, and Xerox. The suits assert two patents from the same family that both relate to fax-over-IP (FoIP) with time-based polling (5,826,026, 6,216,156). The asserted patents have not been previously litigated. Google’s Cloud Print service is at issue in each suit, and the service along with printers manufactured by defendants that are compatible with the service are accused of infringing the asserted patents.
