Trademark Thoughts with Tiffany™: What Does “Likelihood of Confusion” Mean?
One of the most common reasons the United States Patent and Trademark Office (USPTO) refuses to register a mark is because of “likelihood of confusion” with an existing registration or earlier application. Understanding what likelihood of confusion is can help you choose a better name and avoid a costly setback.
The core question:
Would ordinary consumers be likely to think the two products or services come from the same source?
USPTO examiners usually look at two things:
How similar are the marks? This covers appearance, sound, meaning, and overall impression. The marks don’t have to be identical. Similar spelling, a shared dominant word, or the same meaning in another language can be enough for your application to be rejected.
How related are the goods or services? Similar names for unrelated products or services may coexist. Similar names for closely related products or services often can’t.
Common misunderstandings:
“My name is spelled differently.” Slight spelling changes rarely avoid confusion if the names sound the same.
“We’re in different industries.” If the products are related or sold through the same channels, that may not help.
“They aren’t using it anymore.” A registration can still block you until it’s cancelled or expires.
How to reduce risk:
Search before you file, think about how your name sounds and reads next to similar ones, and be realistic about how close the products or services you’re offering are to existing brands.
A refusal isn’t always the end. In some cases you can argue that the marks are different enough, narrow your description of goods or services, or negotiate with teh other owner. However, it’s much easier to avoid the problem up front.
