But you cannot say he is not Satoshi the inventor of Bitcoin. After all, look at all of his patents and now even the US government is awarding copyrights to him which can ONLY be given to the original author. It's a fact: CSW is Satoshi.
How does this factually prove anything about Satoshi?
The US copyright office will award you the same copyright registration if you pay the fee. They simply act as a record keeper of who files copyright registrations. The validity of any given copyright claim and disputes over ownership are matters for the federal court system, not the copyright office. The copyright office doesn't care and they aren't making a judgment as to who Satoshi really is.
