What did he eventually gain from claiming to be Satoshi when he had zero chance of proving it in or out of a Court of law?
He had some successes - from intimidating devs to quit, to the point when a judge ruled that Cobra has to filter UK users from accessing the whitepaper at bitcoin.org.
I expect that he thought that his bullshitting will convince eventually everybody, at least until the point he gets the patents he wanted.
There may also be that he didn't want to go this far, he expected to only con some non-technical rich peeps to get an easy life, but it all went on with his backer(s) pushing him into this... shit show.
I really hope it's over.
Now, he will be the laughing stock in the crypto community. Because the truth is, if he really is Nakamoto, it is easy to prove because he can just sign one of the early bitcoin addresses that Satoshi was using. But instead, he pushed himself to be the Satoshi who didn't have very solid proof in front of the court of law.
I don't know if he will retaliate after this ruling. But he should stop his madness, before he got the label as the "crazy guy" in crypto world. Or he's been already is known to a lot as the crazy one.
