Discovery Communications Inc. (NASDAQ:DISCA) has filed a lawsuit against Amazon.com, Inc. (NASDAQ:AMZN). Discovery Communications said that this is a procedural move and not a new lawsuit.
Discovery accuses Amazon.com of infringing patents that cover e-book delivery and security for the Kindle reader. Discovery filed the a patent infringement case in March 17, 2009 and they moved the patents to a separate corporate entity.
Discovery owns a few educational cable TV stations such as Discovery Channel and Animal Planet. “The new lawsuit was brought because the patents at issue in the original lawsuit were recently assigned to Discovery Patent Holdings LLC,” stated a Discovery spokeswoman.
Discovery Communications was issued the patents in 1999 and 2007. The case was filed at the U.S. District Court in the District of Delaware, No. 09-00178.
