EFF goes to court, quashes patent troll’s attempt to grab donor names
That got the company special attention from the Electronic Frontier Foundation, which crowdfunded a challenge to the Personal Audio patents. EFF asked donors to help raise $30,000 to file an "inter partes review" at the US Patent and Trademark Office. That goal was quickly surpassed, and EFF ultimately received about $80,000 from more than 1,300 donors upset about the "podcasting patent."
In January, Personal Audio sent a subpoena to EFF, demanding the full list of donor names. It believes some of those names are connected to companies it has sued in Texas. Those include NBC, CBS, and Fox, as well as the HowStuffWorks podcast (Discovery Channel), Ace Broadcasting (which produces Adam Carolla's podcast), and a smaller Internet radio company called TogiNet.
