Discovery sues Amazon over Kindle

Media company Discovery Communications filed a lawsuit against Amazon.com on Tuesday, accusing the online retailer's Kindle of infringing its patent on electronic book technology, writes Reuters.

The lawsuit claims that both Amazon's Kindle versions have infringed one or more of the claims on a patent that Discovery founder John Hendricks received in November 2007.

The patent deals with encryption technology for the distribution of digital books. Discovery founder John S. Hendricks claims he invented a secure, encrypted system for the selection, transmission, and sale of electronic books.
