There is a patent. I applied for a design patent. Can I apply for a patent for invention or utility model again?

Theoretically, after applying for a design patent, you can apply for a patent for invention or utility model because there is no conflict.

But the problem is that appearance patents are completely different from utility models and inventions.

I don't think it's easy to handle.

From the perspective of patent law, it is impossible to confirm the infringement of the use of appearance patents.

However, you can start with other laws, such as the copyright of graphic files. I suggest you consult a lawyer.
