Can I apply for a patent for the modeling design of ceramic ornaments?

You can definitely apply for an appearance patent, as long as you find someone to help you check whether it is registered. The appearance price is 800 each. Just find a formal license. However, if you need money to apply for a certificate, you have to pay an annual fee to maintain the guarantee period of 10 year, which is cheaper in the first three years and then increases every three years. It's hard to stop others from stealing unless you are willing to take the time to crack down on those who steal from you. It needs to be solved through legal channels. You can send a warning letter from a lawyer first, and you can claim compensation if the circumstances are serious.
