Texas Instruments Ordered to Pay $3M for Infringing US Ethernet Patent

  • September 25, 2014

Texas Instruments (TI) infringes a patent asserted in litigation by US Ethernet according to the court’s final judgment, which also included an award of $3 million in damages. US Ethernet asserted four patents when it sued TI, along with Brother International and Canon, in September 2011. By the time the case reached trial, the other two defendants had been dismissed and only three patents were still at issue (5,434,872, 5,530,874, 5,732,094). An initial jury verdict in April 2011 found that the three patents are valid and rejected TI’s arguments of invalidity on obviousness and anticipation. A separate hearing was held as to infringement and dealt only with the ‘872 patent. The jury found that TI’s accused products infringed, and the court awarded US Ethernet $3 million in damages in its ruling. TI’s laches defense was also rejected in the final judgment.
