German chipmaker Infineon Technologies AG has settled its patent infringement claim against Atmel, and both companies have agreed to seek dismissal of all pending patent infringement claims. Infineon and its subsidiary Infineon Technologies North America Corp. initiated proceedings in April 2011 when they filed a complaint against Atmel in the U.S. District Court for the District of Delaware. The patents in the suit and countersuit are related to microcontrollers.

Infineon and Atmel have settled the dispute through a broad patent cross license. As part of the agreement, Atmel will pay Infineon an undisclosed sum. The companies did not disclose the specific terms and conditions of the license.
