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

When I was at the stage of ensuring my client's business name wasn't stepping on any toes, trademark-wise, I followed the outlined steps for both federal and state-level checks.

Federal Trademark Check (Through the USPTO)

The USPTO manages federal trademarks. You can use their online search system, known as the Trademark Electronic Search System (TESS), to search for federally registered trademarks [1].

On the USPTO website, navigate to the TESS search page. You can conduct a basic search if you have the exact name you want to check or use the advanced search for more complex queries.

Pay close attention to the results that are similar in sound, appearance, or meaning to the name you want to use. Even if the name is not an exact match, a similar name in a related industry could pose a conflict.

State Trademark Check (SOT Website)

The SOT database primarily contains information about business entity names [2]. it's a good starting point to ensure your desired business name isn't being used within the state.

However, for trademarks specifically, you might need to look for a dedicated state trademark search section or contact the state's Division of Corporations for guidance.

Similar to the federal search, review any trademarks that could potentially conflict with your business name. Pay attention to trademarks in similar industries or those that sound or look similar to your desired name.

These are the reasons to perform an LLC search:

  • Avoid legal issues: Performing a trademark search can help you avoid legal conflicts by ensuring that your desired business name or logo isn't infringing on someone else's registered trademark, potentially saving you from costly litigation.
  • Unique brand identity: A thorough search helps ensure that your brand name or logo is unique, allowing you to build a distinctive identity in the marketplace that customers can easily recognize.
  • Prevent rebranding: Discovering a trademark conflict after you've started your business can lead to rebranding, which is not only expensive but can also result in losing customers and brand recognition.
  • Market research: A trademark search can double as market research, giving you insight into your competitors and how crowded the market might be for your brand concept.
  • Compliance with registration requirements: If you plan to register your trademark, conducting a search is a crucial step to ensure compliance with registration requirements and increase the likelihood of your application being approved.
  • Protect your business nationwide: For businesses planning to operate across the U.S., a federal trademark search ensures that the name is available nationwide, offering broader protection than a state trademark alone.
  • Enhance Brand Value: A unique and legally protected brand name or logo adds value to your business, making it more attractive to potential investors, partners, and customers.
