Discovery Communications filed complaints about Amazon.com infringing patents regarding electronic book delivery and security with its Kindle e-reader product, Reuters reported on Thursday.
Discovery Patent Holdings LLC filed a complaint Wednesday in Delaware's federal district court, claiming infringement upon two patents: the operation of Amazon.com's website and the provision of services for several Kindle devices.
Discovery Communications, which owns several nonfiction and educational television programs, was issued both patents in 1999 and 2007; the organization assigned the patents to Discovery Patent Monday, July 12.
Neither Discovery Communications, nor attorneys for either party provided comment.
*Discovery Communications has asked us to point out that it filed a patent infringement lawsuit against Amazon.com on March 17, 2009. The July 14, 2010 related lawsuit regarding the same patents was brought by Discovery Patent Holdings, LLC, which is a subsidiary of Discovery Communications, Inc. The new lawsuit was brought because the patents at issue in the original lawsuit were recently assigned to Discovery Patent Holdings, LLC.
