The Likelihood of Confusion Standard Revisited

In the fast-paced world of business, trademarks play a crucial role in distinguishing one brand from another. To protect the uniqueness and identity of their brands, companies rely on trademark law, which is guided by the “likelihood of confusion” standard. This standard determines whether consumers are likely to be confused between two trademarks, and serves as a vital safeguard against brand dilution and infringement. In this article, we will delve into the likelihood of confusion standard in trademarking and its significance in today’s competitive branding marketplace.

The likelihood of confusion standard is a fundamental principle in trademark law used to assess the similarity between two trademarks. Under this standard, the courts consider multiple factors to determine whether there is a significant risk that consumers might confuse two trademarks. These factors typically include the similarity of the marks, the relatedness of the goods or services, the channels of trade, the strength of the mark, and the overall impression created by the trademarks.

Key Factors to Consider

Several key factors contribute to the determination of the likelihood of confusion.

1.      The similarity between the trademarks themselves. Courts examine the visual, phonetic, and conceptual resemblance of the marks to assess their overall similarity. The greater the similarity between the marks, the higher the likelihood of confusion.

2.      The relatedness of the goods or services is another essential factor. If two trademarks are used on similar or closely related products, there is a higher likelihood of confusion. For example, if two companies use similar marks for selling identical or related products, consumers may mistakenly believe that the goods or services originate from the same source.

3.      The channels of trade and the degree of consumer care are considered. If the trademarks are used in the same or overlapping channels of trade and if consumers typically make impulsive purchases or do not exercise a high level of care, the likelihood of confusion increases.

4.      The strength of the mark also plays a role. A strong and well-known mark is afforded greater protection, as consumers are more likely to associate it with a particular brand.

Understanding Your Trademark Attorney Opinion Letter

If you’ve worked with our law office and received an Attorney Opinion Letter pinpointing a potential conflict with another brand based on likelihood of confusion, you may disagree on the relatedness between your goods and/or services and those offered by other companies. But the likelihood of confusion standard can be quite strict and broadly applied. Even slight relatedness or similarities in the goods/services offered and the marks being applied for may justify a refusal in the eyes of a discerning USPTO Examiner. What’s more, there is an element of subjectivity in the USPTO trademark review process – every Examining Attorney is beholden to the same standard of review, but there are variations in how each Examiner considers and interprets that standard for each mark being reviewed.

How to Improve Your Chances for a Successful USPTO Review

Things to consider to ensure a fairly smooth USPTO trademarking process and working with our trademark attorneys. First, ensure your mark is as unique as possible and does not resemble any other marks used in connection with the same or similar goods/services. Our team of trademark attorneys, through our Comprehensive Trademark Search service, attempt to identify possible conflicts with prior filed or registered trademarks. Following the Search, you may have to modify your mark, or select a new mark or add a logo design.

Second, consider whether your goods/services offered for sale could be within the “natural scope of expansion” for another’s registered goods or services. For example, if there is a registered mark for jewelry (Class 14) or handbags (Class 18), you may have difficulty registering the same or a similar mark for clothing (Class 25). These are related goods and frequently sold or offered for sale together.

Finally, consider where and to whom your goods/services will be offered for sale. If there is overlap in the stores or locales where the goods/services may be offered, there is a greater likelihood that the Examiner may find a likelihood of confusion.


For businesses, the likelihood of confusion standard is essential for safeguarding your investment in brand development and marketing. It enables companies to build strong brand identities and reputations, fostering consumer trust and loyalty. Moreover, the likelihood of confusion standard promotes marketplace transparency, as it allows consumers to make informed decisions based on accurate brand associations.
