Macronix has filed patent infringement complaints against Spansion and certain of its customers involving Spansion’s non-volatile memory devices, including microcontroller units and flash memories.

Macronix has taken this step to address Spansion’s widespread infringement of Macronix’s patent rights as well as the infringement that arises when Spansion’s customers import products containing infringing Spansion’s devices into the U.S.

Recently, Allied Telesis stipulated to an ITC consent order, in which Allied Telesis acknowledged the validity of Macronix’s patent claims at issue in proceedings involving the consent order.

As a result, upon ITC’s approval, the stipulated consent order prohibits Allied Telesis from importing into the U.S. or selling in the U.S. after importation any product containing infringing Spansion devices.

“We are glad to see that Allied Telesis acknowledged the strength of Macronix’s patent claims as shown by its stipulation for entry of an ITC consent order. This action demonstrates that Spansion’s customers are losing confidence in Spansion in the face of Macronix’s strong intellectual property.” said Arthur Yang, President of Macronix America, Inc.
