Discovery sues Amazon.com over Kindle patent

(AP) -- Discovery Communications Inc. says the Kindle electronic book readers from Amazon.com Inc. violate a patent that Discovery registered in 2007. Discovery sued Amazon in Delaware on Tuesday.

Discovery spokeswoman Michelle Russo said the company is seeking "fair compensation" through damages, future royalty payments and legal fees but will not seek an injunction stopping sales of the Kindle.

An Amazon.com spokeswoman declined to comment.

Discovery, which runs the Discovery Channel and Animal Planet cable TV networks, said Amazon.com was "willful" in infringing the patent. Discovery says the patent covers the security of electronic book files.

Amazon.com shares were up 3.6 percent to $69.40 in afternoon trading, while Discovery shares were up 9 cents at $16.75.
