What Makes a Trademark Strong?

A trademark that can differentiate your goods and/or services in a unique and distinctive way is considered strong. On the contrary, trademarks that have a limited ability at uniquely identifying the source of goods (i.e. because they are descriptive or suggestive – alluding to the product without describing it directly) are considered weaker.

The U.S.P.T.O. uses the following spectrum classification to classify trademarks from strongest to weakest: Fanciful, Arbitrary, Suggestive, Descriptive and Generic.
