From a press release from the patent troll:
"When Personal Audio first began its litigation, it was under the impression that Carolla, the self-proclaimed largest podcaster in the world, as well as certain other podcasters, were making significant money from infringing Personal Audio’s patents. After the parties completed discovery, however, it became clear this was not the case. As a result, Personal Audio began to offer dismissals from the case to the podcasting companies involved, rather than to litigate over the smaller amounts of money at issue."
