Anyone can make any case appealable to the Federal Circuit just by throwing in any claim arising under the patent laws. You can add an obviously bogus and unrelated patent claim in initial filings and then drop it in pre-trial and still guarantee biased CAFC jurisdiction.

You could probably force a random criminal trial into the CAFC with a little creativity. It's really easy to go to CAFC if you want to. And if you're abusing intellectual property law, you really want to because they're corrupt like a Venezuelan payday loan used car dealer.
