How to Check If A Business Name Is Trademarked in New Hampshire?

To check if a business name is trademarked in New Hampshire, search the USPTO database, visit the state's database, or consult a trademark attorney.

Before establishing your brand, it is crucial to ensure the name chosen is unique and doesn't infringe on existing trademarks [1]. According to the New Hampshire Department of Revenue Administration, as of January 2022, approximately 80% of businesses in the state registered their business names with the Secretary of State's office to safeguard their intellectual property rights.

Checking against federally registered trademarks also avoids legal complications and ensures your business name stands out.

Here's how you can check if a business name is trademarked in New Hampshire:

1. Search the USPTO Database

Start by visiting the USPTO's Trademark Electronic Search System (TESS).

This database allows you to search for registered trademarks and pending trademark applications across the United States, including New Hampshire.

You can use various search strategies, from simple to complex, depending on the uniqueness of the business name you're researching.

It's important to look for names that are identical and similar enough to confuse, as these could potentially conflict with your intended business name.

2. New Hampshire State Database

Although trademarks are registered at the federal level through the USPTO, it's wise to check the New Hampshire state database for business registrations.

Visit the New Hampshire Secretary of State's Business Search to see if the business name is used or registered within the state. According to the New Hampshire Secretary of State's office, approximately 90% of businesses in the state choose to register their business names locally to establish their presence and protect their interests.

While this won't reveal trademarked names, it helps identify businesses that may not have federal trademarks but could still pose conflicts within the state.

3. Consult with a Trademark Attorney

Trademark law can be complex, and similar names in different industries can sometimes coexist without issue.

Consulting with a trademark attorney can provide comprehensive insights and legal advice tailored to your situation.

An attorney can help interpret search results, assess the risk of infringement, and advise on the likelihood of trademark registration success.

They can also assist with the trademark application process, ensuring that your business name complies with all legal requirements and is adequately protected.

Here are several key reasons why you need to perform a detailed search on an LLC business:

  • You can perform a search to verify or confirm business legitimacy.
  • Ensure the business name or logo doesn't infringe on existing trademarks.
  • A search is crucial in performing diligence for an LLC before investments.
  • A search is important for evaluating potential business partners.
  • Useful for understanding industry trends and positioning.
  • Performing a search helps you check a business before completing a deal to mitigate risks in business transactions.
