Are hyperlinks illegal? Electronic Frontier Foundation Media Release: EFF Defends Internet Linking – Asks Court to Rehear Ditto.com Case. San Francisco – The Electronic Frontier Foundation (EFF) today filed a brief on behalf of Ditto.com, urging the U.S. Ninth Circuit Court of Appeals to reconsider a ruling that threatens to make all linking on the World Wide Web a copyright infringement. The Ninth Circuit court created a novel legal rationale. It found that linking to a website without permission infringes the public display rights of the website owner.
