The bulk of a large tranche of patents that Daedalus Group LLC picked up from IBM last fall was assigned to Daedalus Blue LLC in late January. A day later, the remainder of those assets—many of them generally related to various aspects of self-driving vehicles—was transferred to Slingshot IOT LLC, a Maryland entity created one week earlier. Daedalus Blue has already begun litigating its portion of that portfolio; given its apparent origins, Slingshot IOT may not lag by much.
