University of Minnesota Sues Wireless Carriers over 4G Networks

  • November 12, 2014

The Regents of the University of Minnesota filed suit against AT&T, Sprint, T-Mobile, and Verizon, asserting a group of patents that have not been seen in previous litigation (7,251,768, 8,588,317, 8,718,185, 8,774,309, RE45,230). The patents relate to wireless communication and transmission of wireless signals, and defendants’ 4G LTE networks are accused of infringement. With the exception of the ‘768 patent, the asserted patents issued within the last year; the ‘768 patent issued in 2007. The university filed one previous suit in 2007, which concluded in July 2013 when the Federal Circuit Court of Appeals upheld a district court’s grant of summary judgment of invalidity as to the asserted patents. The patents asserted in the previous suit relate to a biomedical device. 11/5, District of Minnesota, 0:14cv04666, 0:14cv04669, 0:14cv04671, 0:14cv04672
