Personal Audio is a company that doesn’t actually produce podcasts. They merely demand cash from those who do, claiming they are infringing on a patent. Last week, the company dropped one such lawsuit against comedian/podcaster Adam Carolla after realizing he doesn’t make all that much money. But here’s the thing. Carolla won’t let them drop the case. He and his company intend “to continue to vigorously defend Personal Audio’s lawsuit and to pursue its counterclaims against Personal Audio, which include a request that the Personal Audio patent be invalidated so that Personal Audio cannot sue other podcasters for infringement.” How did Personal Audio get the patent in the first place? Well, they used to release magazine articles on cassette tapes.
