Is Discovery Communications Working on eBook Reader?

Discovery Communications (DISCA) has filed for a patent on an e-book reader, the Baltimore Sun reported over late last week.

The Sun notes that Discovery, which owns Discovery Channel, Animal Planet and other cable properties, filed a patent for the device in February; but the Sun notes that the patent filing was not made public until last Thursday.

The story reports that “diagrams included with Discovery’s patent application…depict a rectangular device with physical controls for user navigation.” The device would be for reading e-books and “providing for e-commerce.” As the Sun notes, Discovery already holds a patent on some security and copy protection features, and earlier this year sued Amazon.com (AMZN) for alleged infringement by the Kindle.
