The transfer of multiple patents from Intellectual Ventures LLC (IV) on October 28, 2016 to various subsidiaries of Monument Patent Holdings, LLC formed the bulk of recorded assignments seen by RPX during the first half of December. A first of those subs (Preferential Networks IP, LLC) has already asserted one of the patents that it received in litigation, while the other two (Equalizer IP, LLC and Wireless Switch IP, LLC) have yet to file suit. Monument recently recorded the assignment of two e-commerce patents to its Landmark Networks, LLC subsidiary, which also just filed suit, as have NPEs Interactive ToyBox, LLC and Vesper Technology Research, LLC, both of which likewise recorded the assignment of patents asserted in early December.
