Louisville, KY asked in Intellectual Property and Trademark for Ohio

Q: Can I use "Doom" for a lit-up sign product name?

I am planning to sell a sign that lights up and displays the word "Doom." I want to know if I can legally use "Doom" in the product name. The product itself will be branded this way, but it won't necessarily extend to a broader product line.

A: You can generally use the word "Doom" for your lit-up sign product name, as common words aren't automatically off-limits legally. However, it's important to ensure you're not infringing on existing trademarks. A quick search through the U.S. Patent and Trademark Office database will help you determine if "Doom" is already trademarked in a similar product category.

Even if "Doom" is trademarked, you might still be able to use it if your product isn't likely to cause confusion among consumers. Consider whether your sign resembles, references, or implies association with any existing products or brands named "Doom." If there’s no connection or likelihood of confusion, the risk of infringement decreases.

To minimize any potential legal issues, ensure your branding clearly differentiates your product from existing trademarks. If there's any uncertainty, it would be wise to consult with a trademark attorney. Taking these steps can help you confidently move forward with your "Doom" sign.
