Electronic Frontier Foundation:

San Francisco – The U.S. Patent and Trademark Office (USPTO) invalidated key claims in the so-called “podcasting patent” today after a petition for review from the Electronic Frontier Foundation (EFF)—a decision that significantly curtails the ability of a patent troll to threaten podcasters big and small.

This is excellent news. The idea that a patent derived from the cassettes-by-mail era could have stifled podcasting? Chilling.
