Today EFF filed our response brief in the appeal of our successful challenge to Personal Audio’s podcasting patent. Back in April 2015, the Patent Trial and Appeal Board (PTAB) ruled in our favor and invalidated all of the patent claims we challenged. Personal Audio appealed this decision to the Federal Circuit.

It's time to take a closer look at EFF's recent victory against bogus patents and highlight what we and others concerned about our patent system are up against. The United States Patent and Trademark Office (USPTO), acting on our request for review, last week invalidated claims from a patent Personal Audio LLC was using to assert that it invented podcasting.  At stake was the right of bloggers, podcasters, and broadcasters to air content, including popular shows like "This American Life"  and "Stuff You Should Know," online and operate their websites free of costly "settle or we’ll sue" threats from Personal Audio. The USPTO's decision works to stop the self-described "holding company" from using these patent claims to go after more companies, after previously targeting comedian and podcaster Adam Corolla, CBS, and others with patent lawsuits.
