Kindle sparks lawsuit from Discovery

Amazon book reader violates patent, network firm says

NEW YORK -- In the latest legal tussle between a media and a dot-com, cable network firm Discovery Communications has sued, arguing that its successful Kindle electronic book readers violate a patent that Discovery registered in 2007.

Discovery filed the lawsuit Tuesday in Delaware, saying's infringement of a patent covering e-book file security was "willful."

The company cited founder and chairman John Hendricks' role in the development of digital content and delivery services in the 1990s. Among other things, his work included inventions of "a secure, encrypted system for the selection, transmission and sale of electronic books," Discovery said.

"The Kindle and Kindle 2 are important and popular content delivery systems," said Discovery general counsel Joseph LaSala Jr. "We believe they infringe our intellectual property rights, and that we are entitled to fair compensation." officials couldn't be reached for comment.
