Hi there, my name is XXXXX XXXXX I'm a business law attorney with experience in all aspects of business law. I'll do my best to assist you.
Your concern here would be trademark infringement. If you used a name already associated with another entity, which would be confusing to consumers, you might be liable for infringing on their trademark. If you have the exact same name in the same industry, there is a very high likelihood of a finding that the names would be confusingly similar.
While you don't necessarily need a legal registration of a "brand" and such, it is prudent to take a few simple steps. Probably the easiest way to address such an issue would be to register a fictitious name, or "DBA
", with the PA Department of State. This would associate that name with your existing business entity. That would allow you to use the name in a legal sense (for banking, official forms, etc.). You can find the appropriate form here: http://www.dos.state.pa.us/portal/server.pt/community/corporation_bureau/12457
You should of course choose a name that is unique, and would not be confused with any other entity, particularly in your location and industry. You should do a Google search and a US Trademark Office search to at least get a basic idea if anyone else has a right to it - that should help prevent a repeat of the situation you're in. Particularly once you start using and investing in your brand, changing it would not be such a simple matter. Getting an opinion from a trademark attorney prior to using the brand is always a good idea. Also, consider registering your brand as a trademark with the US PTO for additional protection.
