After receiving a patent portfolio directly from Intellectual Ventures LLC (IV) late last year, the Three Affiliated Tribes of the Fort Berthold Reservation, North Dakota—which made headlines in 2017 when it launched a campaign amid the debate over tribal sovereign immunity—has acquired a second portfolio of IV assets, this one by way of a deal with a different Native American tribe. The assignment, which was executed in early August, was closely followed by another notable acquisition by the Three Affiliated Tribes—this one involving a group of patents developed by Pantech.
