Affinity Labs has sued both Apple and car audio maker AAMP over audio technology patents. Affinity accuses the companies of violating two U.S. patents, one for a "Content Delivery System and Method" and the other for a "Method for Managing Media." Affinity contends that the iPhone violates both patents, while the iPhone and iPod touch allegedly violates the first patent only.
Apple has not yet commented on the suit. You can read the full complaint here.
