T-Rex Property AB has filed suit against another two defendants, capping off the May escalation of a litigation campaign that has targeted over 60 companies since its start in June 2012.

The two complaints each allege infringement of three patents that have been asserted in various combinations over the course of the entity’s campaign: two that generally relate to the real-time display of information on public billboards (RE39,470; 7,382,334) and one that relates to advertising on them (6,430,603). As in its previous filings, the NPE’s most recent lawsuits target devices and systems related to digital billboards and advertising.
