I purchased a domain that I want to use as my trademark for my game, however, I noticed someone is already using the name, unfortunately. I have a few questions:
1. Does an unregistered trademark give you complete authority over the name of your trademark. For example, can I use the same name as long as my logo is completely different?
2. If someone has a trademark on "Company Name," am I allowed to put a trademark on "CompanyName?"
3. How does an unregistered trademark expire? I've seen a ton of website with an unregistered trade with "Coming soon" on the page, and they sit there for 10 years. What's to stop someone from creating a million unregistered trademarks so that others can't have them?
If you can share the answers to any of these questions, I would really appreciate it. Thank you.
