Just register your name by getting a business license. BTW, unless the other party is a photographer, he/she can use the same name and there is nothing you can do. Ex: You can be ABC Photography and he/she can be ABC Plumbing. They can even have a similar logo and there's nothing you can do.ahh yiks, i wanted to trademark my name cause i found out that someone else has it. should i just let it go?
