Navigating the Risks: Cease and Desist Letters Against Parties with Superior Common Law Rights
When protecting your brand and trademark rights, sending a cease and desist letter is often seen as a standard first step. However, this approach carries significant risks when the recipient may have superior common law trademark rights. Common law rights arise from actual use of a mark in commerce, even without federal registration. In some cases, these rights can outweigh a later-filed federal registration, especially when the other party has been using their mark for a longer period or in a specific geographic area.
Failing to properly assess the other party's rights before sending a cease and desist letter can lead to expensive litigation, damage to your brand's reputation, and even the loss of your own trademark rights. This article explores the key legal, strategic, and business risks involved and offers guidance on how to proceed more carefully.
Understanding Common Law Trademark Rights
Before diving into the risks, it's important to understand what common law rights actually are. In the United States, trademark rights can exist even without federal registration. These are known as common law rights and are based on actual use of the mark in commerce within a specific geographic area.
Key characteristics of common law rights include:
They are limited to the geographic areas where the mark has been used and where consumers recognize it.
They can be superior to a federal registration if the common law user began using their mark before the federal registrant's priority date.
They are harder to prove and enforce compared to federally registered marks, but they are still legally valid.
If the recipient of your cease and desist letter has been using a similar mark for many years in a particular region — even without registration — they may have strong common law rights that could defeat or limit your claims.
Legal Risks of Sending a Cease and Desist Letter
1. Triggering a Declaratory Judgment Lawsuit
One of the most immediate legal risks is that the recipient may respond by filing a declaratory judgment action in federal court. In this type of lawsuit, the other party asks a judge to declare that their use of the mark does not infringe your trademark rights.
This forces you into litigation on their terms. Instead of you being the plaintiff enforcing your rights, you become the defendant. Litigation is expensive, time-consuming, and public. Even if you ultimately prevail, the cost and distraction can be significant — especially for small businesses.
2. Risk of Losing or Weakening Your Own Trademark Rights
If the other party has superior common law rights, your cease and desist letter could backfire in serious ways. A court may determine that:
Your federal registration is invalid or limited in certain geographic areas.
You do not have exclusive rights to the mark nationwide.
Your registration should be canceled or restricted.
In some cases, aggressively asserting rights you don't fully possess can damage your credibility with the court and weaken your position in future disputes.
3. Creating Unfavorable Legal Precedent
Any lawsuit or formal dispute creates a public record. If a court rules against you because the other party has superior common law rights, that decision can be used against you in future trademark conflicts. Competitors or other parties may cite the case to argue that your enforcement efforts are unreasonable or that your trademark rights are weaker than you claim.
4. Potential Counterclaims
In addition to defending against your claims, the recipient may file counterclaims against you. These could include claims of:
Tortious interference with business relationships
Unfair competition
Bad faith enforcement
Trademark misuse
While not all counterclaims succeed, defending against them adds cost, complexity, and risk to the dispute.
Strategic and Business Risks
1. Damage to Brand Reputation and Public Perception
Cease and desist letters can easily become public, especially in today's digital environment. If the recipient shares the letter on social media, with the press, or in online communities, it can quickly go viral.
When a letter is perceived as aggressive or bullying — particularly when sent to a smaller business, individual, or company with a sympathetic story — it can cause significant reputational harm. Consumers may view your brand as litigious or heavy-handed, which can damage customer loyalty and brand goodwill.
2. Strained or Lost Business Relationships
Sending a cease and desist letter can permanently damage relationships, not only with the recipient but also with mutual business partners, suppliers, or industry contacts. In many industries, relationships are valuable. Being seen as someone who quickly resorts to legal threats can close doors to future collaborations, partnerships, or referrals.
3. High Financial and Opportunity Costs
Legal disputes are expensive. Even if you don't end up in full litigation, responding to a declaratory judgment action, negotiating a settlement, or simply managing the conflict can consume significant time and money. These resources could otherwise be used for growing your business, marketing, or product development.
For small businesses especially, the opportunity cost of being tied up in a trademark dispute can be substantial.
4. Risk of Negative Media or Online Backlash
In the age of social media, aggressive legal actions against smaller parties are frequently criticized online. Negative press or viral backlash can have long-lasting effects on your brand, sometimes far outweighing the original trademark issue you were trying to address.
How to Assess Whether the Other Party Has Superior Common Law Rights
Before sending a cease and desist letter, conduct thorough due diligence. Key steps include:
Researching the other party's history of use (when they started using the mark and in which geographic areas).
Checking for any existing trademark registrations or applications they may have.
Reviewing their marketing materials, website history, and social media presence for evidence of long-term use.
Consulting with a trademark attorney who can help evaluate priority and strength of rights on both sides.
Understanding the strength of the other party's position helps you decide whether a cease and desist letter is the right approach or whether a more collaborative strategy would be better.
Better Approaches When the Other Party May Have Strong Rights
In many cases, especially when the other party has legitimate common law rights, there are better alternatives to sending an aggressive cease and desist letter:
Informal outreach first — A polite, professional email or letter can sometimes resolve the issue without escalating tensions.
Exploring a coexistence or consent agreement — If both parties can operate without causing real consumer confusion, a formal coexistence agreement can allow both brands to continue using their marks peacefully. These agreements are often viewed more favorably than enforcement letters.
Limiting the scope of your demands — Instead of demanding they stop using the mark entirely, you might request modifications (such as adding distinguishing elements or limiting geographic use).
Monitoring the situation — In some cases, the best action is continued monitoring rather than immediate legal action.
Choosing a measured approach can help you protect your brand while avoiding unnecessary conflict and preserving business relationships.
Final Thoughts
Cease and desist letters remain an important tool for enforcing trademark rights, but they should never be used without careful consideration — especially when the recipient may have superior common law rights. Misjudging the strength of the other party's position can lead to costly litigation, reputational damage, weakened trademark rights, and lost business opportunities.
Before sending any enforcement letter, take the time to thoroughly research the other party's rights and evaluate whether a more collaborative solution might better serve your long-term interests. In many situations, protecting your brand doesn't require aggressive legal action — it requires strategic thinking and a clear understanding of the risks involved.
A thoughtful, well-informed approach will help you safeguard your trademark rights while maintaining your business's reputation and integrity.
