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.

Patents continue to peel off from Intellectual Ventures LLC (IV) at a rapid rate, with one of its most recent divestitures, involving nearly 40 US assets, received by a Native American tribe. The transaction came just days after a ruling by the Federal Circuit that inter partes reviews against tribal entities are not barred by sovereign immunity.
