Fairchild sues Infineon over power management patents

EETimes reports: Fairchild Semiconductor is suing Infineon Technologies AG in the U.S. District Courts of Maine and Delaware, claiming some of the German group's CoolMOS and OptiMOS power management devices, as well as its Infineon IGBT and CanPak parts, infringe one or more of eight Fairchild patents.

Long, long ago, Fairchild and Texas Instruments were involved in the fundamental lawsuit over patent rights to the integrated circuit.

There is indication that the lawsuits arose after a breakdown in licensing talks. Reuters reported: Infineon and Fairchild have engaged in cross-licence negotiations, but the talks recently soured, ultimately leading to the lawsuit, according to Fairchild.
