Does "Notice of Granting Patent Right and Handling Registration Procedures" mean that the patent has been approved?

This notice shows that your patent has passed the examination and is in the "authorized" state. As long as you register and pay the fee, you can get a formal "patent certificate".

But if you insist on not going through the final formalities, the patent will still not be authorized and naturally will not be protected. In other words, "you died at the gate of victory." .
