I'm sure there are, but I would put it in the same bucket as the MP3 decoding libraries that have been included in Linux distros behind a checkbox for ages. If you tried to ship a product in the US based on this, I would expect to spend some time getting to know your lawyer. But for personal use, I wouldn't expect any trouble.
Not exactly the same situation as Ubuntu - the MP3 decoding checkbox downloaded Fluendo's decoder, which was actually properly licensed. But otherwise you're correct (FYI, there are EU and JP patents too).
