Why do I need to search other trademarks?

If you're currently using or plan to use a trademark, it's always a good idea to see if there are similar marks that could be confused with yours, or might affect your ability to use and protect your trademark. If there are potentially confusing trademarks registered with the USPTO, those could affect your chances of registering your own mark. Also, if there are any potentially confusing marks already in use by businesses—even marks that haven't been registered—these could affect your ability to register or use your trademark.

What is considered a trademark conflict?

A conflict exists when one trademark is confusingly similar with another trademark already registered and/or being used in commerce. The principal factors used to determine if there would be a chance of confusion include:
  • The similarity of the marks
  • The commercial relationship between the products and/or services

In some cases, trademarks that may seem similar can coexist if they're unlikely to confuse a consumer. For example, two trademarks that may seem similar can both be allowed if they're used for unrelated products or services, and are therefore unlikely to cause consumer confusion.

Common questions

Is a search of federal and state trademark databases enough to uncover a possible conflict?
Not necessarily. In some cases, someone may have "common law" trademark rights simply by being the first to use a trademark in commerce—neither federal nor state registration is required for common law rights. Someone with common law rights can challenge your use or registration of your trademark.

For these reasons, it's a good idea to check beyond state and federal registries, such as registered corporate names and use on the internet. These are included in both the WorldScan International and Federal, State, and Common Law packages.
What are trademark classes?
The USPTO trademark classification system divides all goods and services into 45 trademark classes — 34 for goods and 11 for services. There are many goods or services that fall into each class, and they're not always obvious from the class name.

When you file your trademark application, you must select the class of goods or services that your trademark will protect, and you must also identify the goods or services you provide. Your trademark will only protect the goods, services and class that you name in your application.

Learn more about trademark classes.
How do I choose a trademark class?
When you apply for trademark registration, you must identify the class of goods or services that your trademark covers. It's important to choose the right class, because if you get it wrong, you may not be able to register a trademark. And if you do manage to register for the wrong class, you can't change your registration later to name a different one, or to switch from a good to a service.

A comprehensive trademark search can help you identify trademark classes where a mark similar to yours may already be in use.

The USPTO keeps a searchable "trademark identification manual" online to help you find the trademark classification that's right for you. If you're not sure or you have questions, consider one of our legal plans and schedule a consultation with an attorney.
