Is there a patent certificate for a loan?

I can't. According to the law, loans must be guaranteed according to law. Although patent certificate is a kind of right certificate, it can only be used as a right in guarantee (pledge of rights), but patent certificate is not. Therefore, the patent certificate cannot be used as a guarantee according to law. However, if the patent development needs a loan, holding the patent certificate I obtained can be a good support reason and help to approve the loan.
