Screen Shot 2014-08-20 at 3.05.20 PMPodcasting patent troll Personal Audio has agreed to drop its high profile lawsuit against DJ-turned-podcaster Adam Carolla. In court documents filed by the company, and embedded below, Personal Audio agrees to drop all claims against Carolla for his use of the technology underlying podcasting. They also agree to drop claims against a number of other high profile podcasters.

The settlement is interesting because, until now, Carolla had refused to settle, arguing that it was important to fight back against patent trolls on a point of principle. His “Save Our Podcasts” legal defense fund has so far raised close to half a million dollars.

Why he would settle now after promising to fight is unclear, and will remain unclear for at least 40 days. That’s the quiet period agreed by Personal Audio and Carolla before either is allowed to discuss the settlement.
