Last week RPX reported the assignment of the remaining former IBM assets acquired last fall by Daedalus Group LLC to new Maryland entity Slingshot IOT LLC. Most of those assets were transferred in late January to Daedalus Blue LLC, a entity that has subsequently begun asserting a subset of them, filing a case against dronemaker DJI. Last week, Slingshot IOT assigned nearly 20 assets, roughly a third of what it received from Daedalus Group, to Quartz Auto Technologies, LLC, another new Maryland entity, which has also now turned plaintiff, suing Uber (6:20-cv-00126) in the Western District of Texas over six of those patents.

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.
