Do I need to apply for a patent for the works participating in the design award first?

There is no need ~

If you win the prize, the organizing committee will provide you with relevant information.

I majored in industrial design ~ Some of my classmates and I participated in some competitions.

I never said that I would apply for any patent.

If you win the prize, the organizing committee will send you a bill, which actually recognizes your ownership and hopes you can hand it over.
