The comedian in question is Marc Maron. He does a popular podcast, called WTF, out of his garage in California. It's an interview show, with other comedians and artists. Maron recently found an extraordinary letter in his mailbox. This letter said, basically, that by doing his podcast, out of his garage, he was violating a technology patent. His podcast was, according to the letter, illegal.
"They sent a copy of the patent with this letter," Maron says, "which looks like a large bunch of legal gibberish."
