Trademark Registration Applications
Rejection on Grounds of Alleged "likelihood of Confusion"
In the United States, the USPTO rejects trademark applications under Section 2(d) of the Trademark Act if the proposed mark is likely to cause confusion with an existing registration or a previously filed pending application.
The legal standard is not whether the marks are identical, but whether a consumer would mistakenly believe the goods or services come from the same source. To determine this, the USPTO uses a set of criteria known as the DuPont Factors.
1. The Two Primary Factors
While there are 13 total DuPont factors, the USPTO weights the first two most heavily. In many cases, these are the only factors analyzed:
- Similarity of the Marks: Marks are compared in their entirety for similarity in sound, appearance, meaning, and commercial impression.
- Example: "T.Markey" and "Tea Marquee" may be visually different but phonetically identical, leading to a rejection.
- Relatedness of Goods/Services: The products do not have to be the same, only "related" enough that a consumer might expect them to come from the same company.
- Example: A mark for "Hats" might be rejected if a similar mark exists for "T-shirts" because consumers often buy these from the same brands.
2. Other Key Circumstances (DuPont Factors)
If the primary factors are a "close call," the USPTO examines secondary circumstances:
- Trade Channels: If both products are sold in the same stores (e.g., both in grocery stores vs. one in a specialized medical supply shop), confusion is more likely.
- Conditions of Sale (Buyer Sophistication): * Impulse Buys: Low-cost items (candy, soap) have a higher risk of confusion because consumers don't spend much time researching them.
- High-Stakes Purchases: Expensive or technical items (cars, surgical equipment) involve "sophisticated purchasers" who are less likely to be confused.
- Fame of the Prior Mark: Highly famous marks (like Nike or Apple) receive much broader protection, making it harder for any similar mark to be registered, even in unrelated fields.
- Number of Similar Marks: If the market is already "crowded" with similar marks for those goods, the USPTO may determine that consumers have learned to distinguish between them based on small differences.
3. Common Misconceptions
An application can still be rejected even if:
- The classes are different: Being in International Class 25 (Clothing) does not automatically protect you from a mark in Class 18 (Leather goods).
- You have used the mark longer: The USPTO generally prioritizes the filing date (priority) over who started using the mark first in the "real world" (unless you file a formal opposition).
- There is no actual confusion: The USPTO does not need to see proof that someone was confused; they only need to prove that confusion is likely.
