ATI pays Cirrus Logic $9m for graphics patents

Settles legal action

ATI and Cirrus Logic have settled their legal dispute with a patent cross-licensing agreement - the standard outcome in such cases.

ATI will also pay Cirrus $9 million. In return, it gets part of Cirrus' intellectual property portfolio

The fight centred on two separate allegations of patent infringement, both made by Cirrus against ATI. One charge related to PC graphics chip patents, and this is essentially what ATI has now bought off Cirrus, which no longer operates in the PC graphics market. Redress for ATI's alleged infringement was sought last May - the other case, relating to an unnamed patent, was initiated in July 1998. ®
