How to Check If A Business Name Is Trademarked in Oklahoma?

You can check if a business name is trademarked in Oklahoma by performing a federal or state-level trademark search.
Before finalizing a business name in Oklahoma, it's crucial to ensure it’s not already trademarked.
Here is how you can go about it:
1. Federal Trademark Search Using the USPTO Database
For the federal trademark:
- Visit the United States Patent and Trademark Office's Trademark Electronic Search System (TESS). This database includes all registered trademarks and pending applications at the federal level.
- Utilize the 'Basic' or 'Expert' search options to input your proposed business name or logo. Searching for variations and similar-sounding names is important to ensure comprehensive results.
- Review the search results carefully. If your proposed name or a similar one appears, it may already be trademarked, requiring you to consider an alternative name or design.
- If you're unsure about the search results or the legal implications, consulting a trademark attorney or a legal expert is advisable for guidance.
2. State-Level Trademark Search: Oklahoma Secretary of State
- Navigate to the Oklahoma Secretary of State's Trademark Section for state-level trademark information.
