A trademark is the best way to protect your business name, logo, and intellectual property at the national level. You have to submit an application and pay some fees to register your trademark with the United States Patent and Trademark Office (USPTO). The USPTO protects you from fraud, copycats, and counterfeits.
You can protect your name and logo at the same time, but each one is considered a separate mark and needs a separate application. For registration purposes, you can seek help from a professional trademark lawyer.
