A federal appeals court affirmed the April 2015 inter partes review (IPR) ruling — a process that allows anyone to challenge a patent’s validity at the U.S. Patent and Trademark Office — that invalidated the so-called “podcasting patent.” “That process was held by a company called Personal Audio, which had threatened numerous podcasts with lawsuits in recent years,” reports Ars Technica. From the report: Back in 2013, Personal Audio began sending legal demand letters to numerous podcasters and companies, like Samsung, in an apparent attempt to cajole them into a licensing deal, lest they be slapped with a lawsuit. Some of those efforts were successful: in August 2014, Adam Carolla paid about $500,000. As Personal Audio began to gain more public attention, the Electronic Frontier Foundation, however, stepped in and said that it would challenge Personal Audio’s US Patent No. 8,112,504, which describes a “system for disseminating media content representing episodes in a serialized sequence.” In the end, EFF raised over $76,000, more than double its initial target. [T]he history of Personal Audio dates to the late 1990s, when founder Jim Logan created a company seeking to create a kind of proto-iPod digital music player. But his company flopped. Years later, Logan turned to lawsuits to collect money from those investments. He sued companies over both the “episodic content” patent, as well as a separate patent, which Logan and his lawyers said covered playlists. He and his lawyers wrung verdicts or settlements from Samsung and Apple.
