Trademark Consent Agreements: When Coexistence Can Overcome a USPTO Refusal
A likelihood-of-confusion refusal can feel like the end of a trademark application. Sometimes it is. But when the applicant and the owner of the cited registration believe their marks can coexist without confusing customers, a carefully designed trademark consent agreement may give the United States Patent and Trademark Office important evidence that registration should be allowed.
The word carefully matters. A short letter that says only “we consent” may carry limited weight. The USPTO evaluates the substance of the parties’ arrangement, the marketplace facts behind it, and the rest of the likelihood-of-confusion record. A useful agreement does more than grant permission: it shows why confusion is unlikely and what the parties will do to prevent it.
What a Section 2(d) refusal means
Section 2(d) of the Trademark Act permits the USPTO to refuse registration when an applied-for mark so resembles an existing registration that consumers are likely to be confused, mistaken, or deceived about source. The analysis does not stop with a side-by-side comparison of the names or logos. It also considers the goods or services, trade channels, customers, purchasing conditions, and other relevant circumstances.
For many applications, the comparison is driven by the descriptions in the application and cited registration. A business may know that it sells a specialized product to a narrow group of customers, but a broadly written identification can make the legal overlap look much larger. That is one reason a response should begin with the refusal itself—not with an immediate request that the registrant sign a form letter.
A trademark attorney can evaluate whether the refusal is vulnerable on the merits, whether an amendment could accurately narrow the application, and whether approaching the registrant fits the applicant’s broader trademark registration strategy.
Consent, coexistence, and concurrent use are not the same thing
The USPTO’s Trademark Manual of Examining Procedure describes a consent agreement as an agreement in which a registrant consents to another party’s registration of an identical or similar mark, or the parties consent to each other’s registrations. An applicant may submit one after receiving a Section 2(d) refusal or in anticipation of a refusal. The examining attorney, however, does not solicit the agreement for the applicant.
A coexistence agreement is often broader. In addition to addressing registration, it may allocate how the parties may use their marks in the marketplace, define product lines or territories, set branding rules, regulate advertising, and establish a process for responding to actual confusion. Depending on the business relationship, the agreement may also address enforcement, future expansion, assignments, and termination.
“Concurrent use” has a narrower technical meaning at the USPTO. It concerns geographically restricted federal registrations obtained through a specific concurrent-use procedure. A consent or coexistence agreement can contain territorial limits, but that does not automatically make it a concurrent-use proceeding or a concurrent-use registration.
Why the parties’ judgment can carry substantial weight
A consent agreement is one factor in the overall likelihood-of-confusion analysis. It does not bind the USPTO or create an automatic right to register. Even so, courts have long recognized that businesses operating in the relevant market often understand the commercial setting better than a paper record alone can reveal.
In In re Four Seasons Hotels Ltd., the Federal Circuit reversed a refusal involving FOUR SEASONS BILTMORE and THE BILTMORE LOS ANGELES. The parties’ agreement did far more than express consent. It limited how and where the BILTMORE wording would be used, barred certain uses by each party, disclaimed an association between the businesses, and required cooperation if confusion arose. The court concluded that the agreement deserved substantial weight.
The current USPTO guidance reflects that principle. Examining attorneys are instructed to give substantial weight to a proper “clothed” consent agreement when it shows that the parties considered their commercial interests and adopted arrangements designed to avoid confusion—unless the other evidence still clearly points the other way.
Why a bare “we consent” letter may not solve the refusal
The USPTO distinguishes a detailed agreement from a “naked” consent. A naked consent contains little more than the registrant’s permission and perhaps a conclusory statement that confusion is unlikely. It may help in a close case, but it gives the examining attorney little information about how the parties reached that conclusion or how they will protect consumers.
This is not a contest to produce the longest contract. The relevant question is whether the agreement presents a reasoned account of the marketplace and workable measures that address the actual confusion risk. Under the USPTO’s current framework, considerations include whether both parties agreed, whether their goods or services move through separate trade channels, whether they will restrict their fields of use, whether they will cooperate to prevent and correct confusion, and whether meaningful coexistence has occurred without reported confusion.
No single provision is mandatory in every case. Evidence of past coexistence is useful only when the duration and conditions make it meaningful. A promise to cooperate can be helpful, but it will be less persuasive if the marks, goods, customers, and trade channels remain essentially identical and the agreement does not explain how confusion will be avoided.
What a stronger coexistence arrangement may address
The agreement should fit the actual businesses rather than copy generic language. Depending on the facts, the parties may consider:
- The marks as used. The agreement can specify wording, logos, house marks, color treatments, or other presentation features that distinguish the parties.
- Goods and services. It can define product categories, service offerings, customer segments, price points, or fields of use reserved to each party.
- Trade channels and promotion. The parties may address retail channels, professional markets, websites, paid search, social-media handles, app stores, distributors, or industry events.
- Geography. Territorial limits may be appropriate where the commercial reality supports them, although online sales can make simplistic geographic divisions difficult to administer.
- Confusion procedures. A practical agreement can require notice, information sharing, and reasonable corrective measures if either party receives a misdirected inquiry or other evidence of confusion.
- Future changes. The contract may address new products, rebranding, expansion, licensing, assignment, successors, and amendments so that the arrangement remains workable as the companies evolve.
Those terms have consequences beyond the application. A restriction that helps obtain registration today might constrain a valuable expansion tomorrow. The parties therefore should treat the agreement as a commercial contract, not merely an exhibit to an Office action response.
When an agreement may still fall short
The USPTO retains responsibility for protecting the public from source confusion. A private agreement cannot require registration when the remaining evidence strongly indicates that confusion is likely.
Risk is higher when highly similar marks cover identical or legally identical goods sold to the same customers through the same channels, particularly if the agreement offers no credible separation. A weak agreement may also fail when its promises conflict with the application’s broad identification, when the claimed distinctions are not reflected in the record, or when the parties have too little experience with concurrent use to draw a meaningful conclusion from the absence of reported confusion.
The legal response still matters. Counsel generally should explain how the agreement fits the relevant likelihood-of-confusion factors instead of simply attaching it. If a truthful amendment to the goods or services will better reflect the negotiated division of the market, that possibility should be evaluated as part of the response.
Approaching the registrant is a strategic decision
Contacting the owner of a cited registration is not a risk-free procedural step. The registrant may decline, seek payment, demand restrictions, investigate the applicant’s use, or conclude that enforcement is necessary. An applicant also may reveal business plans or negotiating pressure by approaching too early.
Before contact, the applicant should consider priority, actual use, the strength of each party’s rights, the cost of rebranding, the value of the application, and the likely alternatives if no agreement is reached. A clearance review through a professional trademark search can also expose conflicts or common-law rights that the initial USPTO refusal does not show.
If discussions begin, the applicant should identify who owns the cited registration, confirm that the signatory has authority, and avoid making concessions without understanding their effect. If the registrant makes statements about both parties’ beliefs or mutual obligations, the USPTO generally expects the document to be signed by both parties or by people authorized to bind them.
The agreement should anticipate life after registration
Registration is only one milestone. A coexistence agreement can shape future enforcement, a possible opposition or cancellation, licensing negotiations, due diligence, and a sale of the business. Ambiguous provisions can become their own source of litigation.
The agreement should make clear whether consent applies only to the pending application or also to later applications, updated logos, related goods, affiliates, licensees, and successors. It should also address how alleged breaches are handled and whether one party’s failure to object affects future rights. Businesses considering broader settlement should coordinate the agreement with their TTAB opposition and cancellation strategy.
A practical path after a likelihood-of-confusion refusal
A disciplined response usually starts by analyzing the cited registration and the examining attorney’s reasoning. From there, the applicant can compare several paths: argue that confusion is unlikely, amend the application where permissible and commercially accurate, pursue consent negotiations, adopt a different mark, or combine more than one approach.
If a consent agreement makes business sense, the strongest record connects the parties’ real-world arrangement to the legal issue. It explains why customers can distinguish the sources, documents meaningful safeguards, and aligns those safeguards with the application presented to the USPTO.
A trademark consent agreement can be powerful evidence, but it is not a magic signature page. Its value comes from careful analysis, credible commercial boundaries, and terms the parties can actually follow.
