Letter of Protest, Trademark Opposition, or Cease-and-Desist: Which Does What?
Trademark disputes · USPTO applications · Enforcement
A letter of protest, a trademark opposition, and a cease-and-desist letter serve different purposes. A protest supplies examination evidence to the USPTO. An opposition formally challenges federal registration. A cease-and-desist asks the other business to change or stop conduct.
Choosing the right approach starts with your rights, the evidence, the application’s status, and the result you want.
You discover a similar brand. Then you discover that the other business has a pending trademark application. Should you write to the examiner, oppose the application, or send a demand letter?
These are not interchangeable versions of the same complaint. They go to different recipients and can accomplish different things. In some disputes, a coordinated strategy uses more than one.
Who receives it, and what can it do?
| Tool | Recipient | Main purpose | Important limit |
|---|---|---|---|
| Letter of protest | USPTO, through its designated procedure | Submit objective evidence relevant to examining a pending application | Does not litigate your private ownership dispute |
| Opposition | Trademark Trial and Appeal Board (TTAB) | Challenge the applicant’s entitlement to registration | Does not produce an order stopping marketplace use |
| Cease-and-desist | The other business or its counsel | Demand a change and potentially negotiate a resolution | Is not a court order |
What is a letter of protest?
A letter of protest is a formal submission under the USPTO’s procedure for third-party evidence concerning a pending application. It is not a letter to the Arizona Corporation Commission, and it is not an informal email asking an examiner to take your side.
The USPTO’s protest guidance calls for an appropriate examination issue, supporting evidence, and a filing fee. Potential issues include descriptiveness, failure to function as a mark, or conflict with a federal registration or earlier-filed pending application.
The USPTO first reviews the submission. If appropriate evidence is forwarded to the examining attorney, the examiner determines what action to take. Acceptance of evidence does not mean the application has been refused.
Can I use a protest to prove I used the name first?
Not as a substitute for litigating common-law priority. TMEP § 1715 identifies a claim based only on earlier unregistered use, without a federal registration or prior-pending application, as inappropriate for the protest process.
You may still have meaningful rights. The point is that the examiner’s procedure is not the forum for resolving that contested history between the businesses.
What about a questionable specimen?
Objective evidence that a specimen is digitally created, altered, or otherwise fails an examination requirement may support an appropriate protest. Identify the specific defect and evidence rather than simply alleging fraud.
A “coming soon” page or residential address alone does not establish nonuse. Review the actual specimen, filing basis, claimed dates, and business activity. Some disputes require evidence and procedures beyond what a protest can provide.
What is a trademark opposition?
An opposition is a contested proceeding before the TTAB. It challenges whether a published application should become a federal registration.
For example, a qualifying opposer may assert priority and likelihood of confusion based on earlier rights. Other grounds may apply, but they require a legally sufficient claim and supporting proof.
An opposition involves pleadings, deadlines, evidence, and potentially discovery and briefing. It is not just sending a longer letter to the examiner. The USPTO provides a separate process for initiating proceedings.
Will winning make the other company stop using the name?
Not by itself. The TTAB decides rights to registration. It cannot award damages or issue an injunction stopping use.
A settlement reached during an opposition might include rebranding or limits on use. But those negotiated terms are different from the relief the Board itself can order. Court proceedings may be necessary to seek an enforceable order stopping infringement.
What does a cease-and-desist letter do?
A cease-and-desist letter communicates asserted rights and asks the recipient to take action. Depending on the facts, that might mean stopping a particular use, changing branding, withdrawing an application, or discussing terms for resolving the conflict.
The USPTO distinguishes such demands from a filed lawsuit. The letter does not itself determine who is right or compel compliance.
A useful demand starts with investigation: ownership, priority, the scope of the parties’ uses, relevant records, and the likely-confusion analysis. The requested action should fit the evidence.
Before sending, consider the possible responses. The other business may cooperate, dispute your rights, reveal earlier use, seek its own legal advice, or escalate the matter. Decide what you are prepared to do if the answer is no.
Do not let negotiations consume the opposition window
Publication in the Trademark Official Gazette ordinarily starts a 30-day opposition period. A proper, timely extension request may preserve additional time under the applicable rules.
A letter of protest does not extend the opposition deadline. Sending a cease-and-desist or exchanging settlement emails does not automatically extend it either. Check the official record and calendar the actual deadline.
Protests are generally best evaluated before publication. A protest filed on or within 30 days after publication must meet a higher evidentiary standard; later submissions are ordinarily untimely. An extension of time to oppose does not extend the protest deadline.
How do we choose a strategy?
Start by separating two goals: preventing a federal registration and addressing marketplace conduct. Then review what supports each goal.
- Your rights: ownership, actual use, dates, geographic reach, and any registrations.
- The other application: serial number, filing basis, identification, evidence, and publication status.
- The conflict: similarities, related offerings, customer overlap, and documented confusion.
- The business objective: rebranding, a narrower use, an agreement, or a registration challenge.
- The budget: investigation, initial action, negotiations, and any contested proceeding.
A protest may address an examination defect while a separate demand addresses use. An opposition extension may preserve time to investigate or negotiate. None of these choices should rest only on frustration that another business has a similar name.
Frequently asked questions
Is a protest a cheaper opposition?
No. It is a different procedure with a narrower role. It may be appropriate for an examination issue, but it cannot replace a contested proceeding when that is what the claim requires.
Should I threaten opposition unless the business rebrands?
First assess whether an opposition is legally supported, timely, and something you are prepared to pursue. A demand should reflect the strength and limits of your position, not imply that the TTAB can order a shutdown.
What if the mark is already registered?
An opposition is generally no longer the relevant registration challenge. Cancellation or another procedure may be available, depending on the grounds, dates, and evidence. Review those options promptly rather than assuming every challenge remains available indefinitely.
Choose the next step with the deadline in view
Bring the application serial number, any publication notice, your use records, and correspondence with the other business. We can evaluate the concern and discuss which work should come first. If a deadline is close, flag it when requesting the consultation.
