Fairchild Files Patent Infringement Lawsuit Against Infineon

November 30, 2008 by Jeff Shepard

Fairchild Semiconductor announced that it has filed a patent infringement lawsuit against Infineon Technologies AG. Fairchild said it believes certain Infineon CoolMOS and OptiMOS branded products, as well as other Infineon IGBT and CanPAK products, infringe one or more claims of eight Fairchild patents.

Fairchild has brought claims against Infineon in the U.S. District Court for the District of Maine and the U.S. District Court for the District of Delaware.

The two companies have been involved in extended cross-license negotiations, and the dispute recently escalated to litigation. The only response from Infineon thus far is a brief comment that the lawsuit was filed in response to a similar case brought by Infineon against Fairchild.

"We are very confident in our position in this ongoing patent dispute and will fight to protect our intellectual property," said Justin Chiang, Fairchild’s Senior Vice President and General Manager, Power Conversion, Industrial and Automotive Products.
