Likelihood of Confusion (2(d)) Refusals: How to Overcome Them

October 7, 2026

The most common substantive reason the USPTO refuses a trademark application is likelihood of confusion, usually called a "Section 2(d) refusal" after the section of the Trademark Act that authorizes it. If you've received one, you're not alone, and it is not necessarily the end of your application. Many 2(d) refusals can be overcome with the right combination of arguments, amendments, and evidence. Here's how they work and the main strategies for responding.

What a 2(d) Refusal Means

Section 2(d) of the Lanham Act (15 U.S.C. § 1052(d)) bars registration of a mark that so resembles a registered mark, or in some cases a previously used mark, that it is likely to cause confusion, mistake, or deception when used on the applicant's goods or services. The examining attorney has concluded that your mark and a cited registration (or an earlier-filed pending application) are too close.

A 2(d) refusal usually appears in an office action. Under current USPTO rules you generally have three months to respond, with one optional three-month extension available for a fee. Missing the deadline can cause the application to be abandoned.

How the USPTO Decides: The DuPont Factors

Examining attorneys and the Trademark Trial and Appeal Board analyze likelihood of confusion using factors from In re E. I. du Pont de Nemours & Co., 476 F.2d 1357 (C.C.P.A. 1973), which the USPTO discusses in TMEP §1207.01 In practice, two factors usually dominate:

1. Similarity of the marks in appearance, sound, connotation, and commercial impression, viewed as a whole
2. Relatedness of the goods or services, including whether they are commonly offered by the same source or to the same customers

Other factors can matter: channels of trade, the sophistication of purchasers, the number and nature of similar marks in use on similar goods, the absence of actual confusion despite concurrent use, and the existence of agreements between the parties.

Strategy 1: Argue the Marks Are Different

Marks are compared as a whole, but differences in sight, sound, meaning, and overall impression can be decisive. Effective arguments may show that:

• The shared element is weak or descriptive, so consumers focus on the other elements
• The marks have different meanings or connotations in context
• The dominant portion of each mark is different

Be careful with arguments based on design elements or stylization. When a cited registration is in standard characters, the USPTO generally treats it as covering any style of display, so differences in fonts or colors often carry little weight.

Strategy 2: Argue the Goods or Services Are Unrelated

Overlap in the general field isn't enough. The question is whether consumers would expect the goods or services to come from the same source. Evidence can include how the goods are actually marketed and sold, the specific nature of each party's goods as described in the identifications, and the absence of third parties offering both. Remember that the USPTO compares the goods as identified in the application and registration, not as actually sold, unless the identifications themselves contain limitations.

Strategy 3: Narrow Your Identification

Sometimes the best move is to amend your goods or services to remove the overlap, for example by deleting items that are closely related to the cited registration or by adding meaningful limitations on the type of goods. You can narrow an identification but not broaden it, so think carefully about what you really need. Clear, precise identifications also reduce future conflicts.

Strategy 4: Show a Crowded Field

If many third parties use and register similar marks for similar goods, the shared element may be considered weak, and consumers may have learned to distinguish between such marks by small differences. Evidence of third-party registrations, and especially of actual third-party use in the marketplace, can support this argument. Quality matters more than quantity: registrations for unrelated goods carry little weight.

Strategy 5: Obtain a Consent Agreement

The owner of the cited registration may agree that confusion is unlikely and consent to your registration. A detailed consent agreement, one that explains why confusion is unlikely and what steps the parties will take to avoid it, is often given significant weight. "Naked" consents with no explanation are less persuasive. Approaching the registrant requires judgment: it can lead to a quick resolution, or it can alert them to a potential dispute.

Strategy 6: Challenge the Cited Registration

If the cited registration is vulnerable, you may be able to remove it:

• Non-use or abandonment. If the registrant isn't using the mark, a cancellation proceeding before the TTAB, or in some cases expungement or reexamination proceedings at the USPTO, may be available.
• Your priority. If you used your mark before the registrant's priority date, you may be able to petition to cancel within the applicable time limits.
• Pending maintenance deadlines. If the registration's maintenance filing is due, it may lapse, so it can make sense to request suspension while the deadline passes.

If the citation is an earlier-filed pending application rather than a registration, the USPTO typically suspends your application until that earlier application is resolved.

Strategy 7: Appeal

If the examining attorney issues a final refusal, you may file a request for reconsideration, appeal to the Trademark Trial and Appeal Board, or both. Appeals take time, so they make the most sense when the mark is important and the arguments are strong.

What If You Can't Overcome It?

Sometimes the refusal is correct, and pushing forward only delays the inevitable. In that case, the refusal is a useful warning. Using a mark that the USPTO considers confusingly similar to a registered mark can create infringement risk. Options include modifying the mark, choosing a new brand, or narrowing your use. Talk through the business risk, not just the registration question.

Avoiding 2(d) Refusals in the First Place

A comprehensive clearance search before filing is the best prevention. It identifies conflicting registrations and applications so you can adjust the mark or the identification before you invest in filing and branding. See also Choosing a Strong Trademark.

The Bottom Line

A likelihood-of-confusion refusal is a serious obstacle, but it's often surmountable. The right response depends on the specific marks, goods, evidence, and the cited registrant's situation. Our office action response team can evaluate the refusal and recommend the most efficient path forward.
