Relationship between HowNet Patent and State Patent Office

If it is a utility model or an appearance patent, as long as it can be found, it means that it has been authorized, which is what you call formal approval.

If it is an invention patent, if you can see the "authorization specification", you have already authorized it; If you can only see the "Application Plan", it means that you are not authorized, and you may still be applying, or you may have been rejected or withdrawn.
