WILMINGTON, Delaware (Reuters) - A patent infringement lawsuit filed on Wednesday against Amazon.com was a procedural move and not a new lawsuit, according to Discovery Communications Inc, which filed the complaint.
Earlier on Thursday, Reuters reported that Discovery Communications filed a lawsuit on Wednesday accusing Amazon.com Inc of infringing patents covering electronic book delivery and security with its Kindle e-book reader.
Discovery said it previously filed the patent infringement case in on March 17, 2009. Discovery said it recently moved the patents to a separate corporate entity and Wednesday’s complaint reflected that move.
Discovery owns several educational and nonfiction cable television 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,” said a Discovery spokeswoman.
Discovery Communications was issued the patents in 1999 and 2007 and has accused Amazon.com of infringing the patents with its website and Kindle electronic book reader.
Amazon.com did not return a call for comment.
Amazon.com shares closed down 1 percent to $122.06 and Discovery shares ended down 0.9 percent to $36.29.
The original case is Discovery Communications Inc v Amazon.com Inc U.S. District Court, District of Delaware, No. 09-00178.
