Earlier this month, RPX reported the launch of new campaigns by apparent IP Edge LLC plaintiffs Noblewood IP LLC, Pixeltide Pathway LLC, and Wikeshire IP LLC—each asserting a former IBM patent. Assignment records made public this week suggest that more such litigation could be coming.

Apparent IP Edge LLC plaintiffs Noblewood IP LLC, Pixeltide Pathway LLC, and Wikeshire IP LLC have each launched an inaugural litigation campaign, Noblewood suing Comcast (NBCUniversal Media), Fox (Fox News Network), New York Times, ViacomCBS, and Virtucom over media streaming tools and services; Pixeltide Pathway suing A.T. Cross, CalAmp (LoJack), Tile, and TrackR over tracking devices and solutions; and Wikeshire IP suing DATAX (Kapsch TrafficCom), Econolite Systems, Iteris, and Teledyne FLIR over transportation analytics tools. Noblewood (one such patent), Pixeltide Pathway (two), and Wikeshire (one) assert former IBM patents that were acquired by Daedalus Group LLC in 2019.
