If a store name is the same as a poem name, is there infringement? What if that poem was famous?

...No, it’s in a different field. Has that poem title been patented? It shouldn't be possible. How is it possible to apply for a patent for poetry? There is a 90% chance of failure.

What name you choose is your own business. There are so many people with the same name in the world, so it doesn’t necessarily mean there is infringement, so of course it doesn’t count.
