U.S. Patent Office revokes key elements of controversial podcasting patent

""This is a patent on updating a Web page, when you really look at it, it's a patent on updating a table of contents where some of the links could go to media files," Nazer said. "This is not the kind of thing that should have been patentable and it certainly wasn't new, even in 1996."

Personal Audio could appeal the U.S. Patent Office decision by taking the case to federal court, Nazer said."
