How to protect yourself from illegal copying from the point of view of the law?

Question

Copyright

Hello. I have a burning question about copyright.
I create websites, I am a designer myself. On many sites I saw a copyright that "The design is protected by copyright, any illegal copying will bring you to criminal liability, article such and such point such and such."
I wanted to know how you can protect your work (website designs, interfaces) from illegal copying. Protect from the point of view of the law.
The topic is relevant. You can also send all your answers to my mail specified in the profile of my account. Thank you.

Talk to a lawyer. If you are a designer and a businessman, it is strange that you have not done this until now.
