On January 15, 2018, Unified filed a petition for inter partes review (IPR) against U.S. Patent 5,966,658 owned and asserted by Iron Oak Technologies, LLC, a well-known NPE. The '658 patent, directed to a "system where a communication path can be automatically selected from a plurality of communication paths based on an attribute," has been asserted against mobile communication companies such as Dell, Huawei, ZTE, Acer and Samsung.
