Apply for a patent for door head design.

Your front door faces the street, and people come and go. Some people like this style. Take some photos with a mobile phone, or ask someone to copy them, not to mention 100% copy, but it shouldn't be a problem to copy a 7788, right? Even if the person who made your door doesn't have a bottom, there is still a great possibility that your door will be copied. Don't worry. It is impossible to apply for a trademark or patent for this, right?
