Should I file a trademark application?

Trademarks, patents, copyrights, domain names, and business name registrations all differ, so it is important to learn whether a trademark is appropriate for you.

A trademark typically protects brand names and logos used on goods and services. A patent protects an invention. A copyright protects an original artistic or literary work. For example, if you invent a new kind of vacuum cleaner, you would apply for a patent to protect the invention itself. You would apply to register a trademark to protect the brand name of the vacuum cleaner. And you might register a copyright for the TV commercial that you use to market the product.
