If veterinary drugs are patented, can they be sold without batch numbers?

Patent approval and veterinary drug product listing approval are two independent systems, which are not related to each other.

Patent authorization can only show that the state recognizes your innovative contribution to society and protects your innovative achievements. You can stop others from using it, but it doesn't mean you can use it.

If veterinary drugs need to sell products, they still need to be implemented according to the approval process of veterinary drugs, and they can only be listed after approval.
