Congratulations on taking the first step towards protecting your brand’s identity through federal trademark registration! However, before you embark on this exciting journey, it’s crucial to conduct a thorough trademark search. In this comprehensive guide, we’ll walk you through the essential elements involved in a comprehensive trademark search, including searching US Federal trademarks, US State trademarks, Common-Law databases, and analyzing the results. Our goal is to emphasize the importance of comprehensive research BEFORE securing a federal trademark registration for your name.

Federal vs. State Trademarks: Why Both Matter

Let’s start by understanding the distinction between federal and state trademarks and why both need to be searched.

Federal Trademarks:

These are trademarks registered with the United States Patent and Trademark Office (USPTO). A federal trademark provides nationwide protection and certain legal benefits, making it crucial for businesses operating on a national or international scale.

State Trademarks:

These trademarks are registered at the state level and offer protection within the specific state where they are registered. While state trademarks are valuable for local businesses, they don’t provide the same level of protection as federal trademarks.

Why You Must Search Both:

A clear name in one jurisdiction doesn’t guarantee safety in the other. Federal and state trademarks are separate entities, and potential conflicts can arise at either level. To ensure comprehensive protection for your brand, it’s imperative to search both federal and state trademark databases.

Determining Likelihood of Confusion

Now, let’s delve into the heart of trademark search: determining whether a likelihood of confusion exists for your proposed trademark. This involves examining similarities in Sound, Appearance, and Meaning.

The SAM Rule for trademarks


Sound analysis assesses whether the proposed mark sounds similar to existing marks when pronounced. Phonetic similarities and the way the marks are spoken are considered. For instance, “I SHINE” and “ICE SHINE” may be deemed confusingly similar in sound.


Appearance analysis involves comparing the visual elements of the marks, including spelling and design. Even minor visual differences might not be enough to avoid a likelihood of confusion. For example, “TRUCOOL” and “TURCOOL” could be seen as confusingly similar.


When evaluating meaning, it’s crucial to consider the message conveyed by the marks. Marks with similar meanings or conveying similar ideas might be deemed confusingly similar. For example, “HOPNOTIC” and “HPNOTIQ” could be seen as conveying the same idea and therefore confusingly similar.

Relatedness of Goods and Services

Even if two marks are found to be confusingly similar, a likelihood of confusion exists only if the goods and/or services associated with the marks are related. This determination is made by considering the commercial relationship between the goods and/or services in your application and those in existing registrations or earlier-filed applications.

The key here is that the goods and/or services don’t have to be identical; they merely need to be related in a way that consumers might mistakenly assume they come from a common source. In essence, it’s not whether the actual goods and/or services are likely to be confused but whether a likelihood of confusion exists as to the source of these goods and/or services.

Relatedness of Goods and Services Example:

In the MARTIN’S case, there were two companies using the name “MARTIN’S” for different food products: one for wheat bran and honey bread and the other for cheese. The court ruled that there was a likelihood of confusion between these marks, even though the products were different. This decision illustrates that in trademark law, the key question is whether consumers could easily mistake one product for another due to the similarity in the brand names.

Here, the court determined “the complementary nature of bread and cheese cannot be ignored, and that the association of identical trademarks with these products is likely to produce confusion when the products are not of common origin.” Basically, the Court is saying that ‘bread’ and ‘cheese’ often are sold together (e.g., sandwiches), same retail outlets (e.g., grocery stores), and even in the same part of those retail spaces (e.g., the deli counter). This ruling emphasizes the importance of avoiding such confusion to protect the integrity of brand identities.

The Significance of Common-Law Research

Common-Law Rights in Business Names: When we talk about common law in the context of business names, we’re referring to rights that arise from using a name in commerce rather than registering it. These rights extend to the geographic area where you operate. In other words, if you’re using a business name in a particular location, you have common-law rights to that name within that geographic area.

Common-Law Rights in Trademarks: Common-law rights also apply to trademarks. Even if a mark isn’t federally or state registered, the user still has certain rights to it within their geographic area of use.

Why Comprehensive Common-Law Research is Crucial:

Avoiding Infringement: By conducting common-law research, you can avoid unintentional infringement of existing business names within your geographic area of operation.

Prior Use Defense: If someone with common-law rights challenges your federal trademark registration, they can assert a prior use defense, demonstrating their rights to the mark in their specific region. This can be a huge problem if their specific region is vital to your business.

Geographic Considerations: Common-law rights are inherently tied to geography. By conducting thorough local research, you can identify potential conflicts specific to your operating area.

So What is Comprehensive Common-Law Research?

Here’s a breakdown of what comprehensive common-law research should encompass:

  • Internet Research: This begins with an extensive online search. A comprehensive search looks at businesses operating under a similar name within your industry. Close attention is paid to social media profiles, websites, and online marketplaces.
  • Domain Names: Checking domain registration databases to identify any domain names that closely resemble your proposed trademark.
  • Company Directories: Resources like Dun & Bradstreet and Business Profile can provide valuable information about businesses operating in your industry and geographic area that use similar names or marks.
  • Public Records: In your comprehensive trademark search, you should see corporate and business registrations, fictitious business names, and trade name registrations.
  • Major Newspapers, Magazines, Wires: Thorough research delves into records of major publications to uncover businesses within your niche that may pose conflicts.
  • Trade Journals: Industry-specific publications often contain information about businesses and trademarks related to your specific niche. These sources can be invaluable for identifying potential conflicts.
Common Law Trademark Search Essentials

In summary, conducting a comprehensive trademark search is a critical step in securing a federal trademark registration for your business or product name. This process involves searching both federal and state trademark databases, along with common-law research. By thoroughly analyzing sound, appearance, and meaning, as well as considering the relatedness of goods and services, you can significantly reduce the risk of encountering legal issues down the road.

Remember that trademark registration is not just about legal compliance; it’s a strategic move to protect your brand’s identity and value. Your brand’s future success depends on it.
