Sound Marks (and Other Unusual Trademarks)
There are things in trademark law called sound marks. They do exist, but in practice, they’re quite rare.
Not just uncommon in theory, rare in real-world use and even rarer in successful registration.
If you think back to classic examples, one that always comes up is the NBC tones. Just a few simple notes. Nothing overly complex or flashy. But over time, those notes became associated with a single source. People began to recognize them instantly, without needing to see a logo or read a name.
And that’s really the foundation of trademark law.
It’s not about creativity for its own sake. It’s about recognition. If a consumer hears something and immediately connects it to your brand, that’s when it starts to function as a trademark.
But here’s where things become challenging.
Getting a sound mark registered isn’t a simple filing exercise. It’s not just about submitting a form and waiting for approval. You’re effectively building a legal case to prove that the sound operates as a source identifier.
That means showing the sound isn’t just background noise or decorative, it actually signals your brand to the public.
In most cases, that requires substantial evidence. You may need consumer surveys designed to measure recognition. Those surveys often need to be created and analyzed by experts. You’ll also need to show long-term, consistent use of the sound in commerce, along with proof that the public has come to associate that sound with your business.
Even with all of that in place, approval is not guaranteed.
A common misconception is that a catchy jingle is enough. It isn’t. The law doesn’t rely on instinct or gut feeling. It relies on evidence, clear, structured, and persuasive evidence.
And that evidence can be expensive to gather.
It’s not unusual for the cost of preparing a strong sound mark application to reach $20,000 or more. In some cases, it can go significantly higher depending on the complexity and the level of proof required.
The same general principle applies to other unusual trademarks.
Take scent marks, for example. Yes, they exist. But they’re even harder to establish than sound marks.
Think about the challenge: how do you prove that consumers recognize a particular smell as your brand? Unlike visuals or sounds, scents are harder to document, harder to standardize, and harder to measure in a consistent way.
Because of these challenges, these types of marks tend to sit in a different category.
They’re not typically where a business begins its trademark strategy. Instead, they’re something that comes much later, after years of building brand recognition and market presence.
In that sense, they’re more like advanced protection. Something you grow into over time, rather than something you pursue at the outset.
Can You Trademark Your Last Name?
Shifting to a more familiar topic, one question comes up frequently: can you trademark your last name?
The short answer is usually no, at least not right away.
The reason comes down to fairness.
Trademark law is designed to prevent one person from monopolizing something that others may reasonably need to use. If your last name is shared by other people, the law generally doesn’t allow you to claim exclusive rights to it.
Otherwise, one individual could effectively block others from using their own name in business, which would create obvious problems.
Because of that, the United States Patent and Trademark Office (USPTO) often refuses applications that consist primarily of a surname. This is known as a “surname refusal.”
That said, there is an important exception.
If your name becomes widely recognized as a brand, it may eventually qualify for protection. This concept is known as acquired distinctiveness, or secondary meaning.
What that means in practical terms is that consumers no longer see your name as just a name, they see it as your business.
Well-known examples include names like Ford or Disney. These didn’t start out as strong trademarks. They became strong over time through consistent use, marketing, and public recognition.
Reaching that point requires effort and evidence.
Typically, you’ll need at least five years of continuous use in commerce, along with consistent branding and a meaningful level of public exposure. You’ll also need to show that consumers actually associate the name with your business.
That evidence can take many forms. It might include customer surveys, reviews, media coverage, sales figures, or advertising data. All of these help demonstrate that your name has taken on a secondary meaning in the marketplace.
Even then, approval is not automatic.
The USPTO will review the application carefully and may still require additional proof. So for businesses just starting out, it’s important to set realistic expectations.
Rather than focusing on locking down a surname immediately, it’s often more practical to build a strong, distinctive brand first. Legal protection can follow as that recognition grows.
Patent Enforcement Across Borders
Turning to patents, one of the most common misunderstandings involves enforcement across different countries.
Many people assume that once they have a patent, their rights extend globally. Unfortunately, that’s not how the system works.
Patent rights are territorial.
This means your patent only provides protection in the country where it is granted. If you want protection in multiple countries, you need to secure rights in each of those jurisdictions.
For example, if a company in China wants to enforce patent rights in the United States, they must have a U.S. patent. And to enforce that patent, they’ll need to work with a U.S.-licensed attorney.
The reverse is also true. A U.S. company seeking to enforce rights in Asia or Europe will need local counsel in each relevant country.
Each jurisdiction operates under its own legal framework, and those differences can be significant.
Some countries have faster court systems, while others may take years to resolve a dispute. Some legal systems are more favorable to patent holders, while others place greater limitations on enforcement.
Damages can also vary widely. In some jurisdictions, the potential recovery may be substantial. In others, it may be relatively limited.
Even the tools available for enforcement differ.
Injunctions, which are court orders to stop infringing activity, may be strong and readily available in one country but harder to obtain in another. Customs enforcement can also vary, some countries actively monitor and block infringing goods at their borders, while others do not.
Because of these differences, patent enforcement is not just a legal issue, it’s a strategic one.
Businesses need to think carefully about where to file, where to invest resources, and how to structure their protection in a way that aligns with their market goals.
A U.S. patent alone does not provide global coverage. Instead, building international protection is more like constructing a wall one brick at a time, with each country representing a separate piece of that structure.
The 40,000 Trademark Issue
At one point, the USPTO made headlines by moving to cancel more than 40,000 trademark registrations tied to filings from China.
That number alone raised significant attention.
The issue stemmed from a surge in foreign filings over a period of several years. While many of these filings were legitimate, others raised serious concerns about compliance with U.S. legal requirements.
Under U.S. trademark rules, foreign applicants must be represented by a licensed U.S. attorney. This requirement isn’t just procedural, it’s intended to ensure that applications are properly reviewed and that applicants receive accurate legal guidance.
In some cases, it appeared that attorney names were being used without meaningful involvement. In other words, applications were being submitted under the name of a U.S. attorney who had not actually reviewed or supervised the filing.
That creates a breakdown in the system.
As a result, the USPTO increased enforcement efforts, conducting more thorough reviews and taking action against problematic filings. Some attorneys faced disciplinary measures for failing to properly oversee applications submitted in their name.
While this may seem like a technical issue, it has broader implications.
It affects processing times, the overall quality of the trademark register, and the level of trust in the system. For businesses that follow the rules and invest in proper filings, stronger enforcement ultimately benefits everyone.
A cleaner, more reliable registry makes trademark protection more meaningful and enforceable.
When a Big Company Files “Your” Invention
Consider a scenario that raises a lot of concern.
You’re a researcher or a student, and you develop a new idea. You present it publicly, perhaps at a conference or in a published paper. Then, sometime later, a large company files a patent application covering that same concept.
What options do you have?
The first and most important question is whether you can prove that you created the idea first.
If you can, there may be a path forward.
Depending on the circumstances, you might challenge the inventorship listed on the patent application, open a negotiation with the company, or even pursue legal action.
One potential issue involves the inventor’s oath.
When someone files a patent application, they are required to declare that they are the true inventor. If that statement is knowingly false, it can raise serious legal concerns and potentially provide leverage in a dispute.
There is also a formal legal mechanism called a derivation proceeding.
This process is designed for situations where one party claims that another derived the invention from them. However, timing is critical. In most cases, you must initiate the proceeding within one year of the other party’s filing date.
Missing that window can significantly limit your options.
Additionally, you may need to file your own patent application as part of the process. This helps establish your claim and provides a foundation for the proceeding.
While these situations can be complex, the key takeaway is that you are not necessarily without recourse. But acting quickly and strategically is essential.
Patent Litigation Fees (Contingency or Not?)
Another common question involves the cost of patent litigation and whether attorneys work on contingency.
The answer is: sometimes, but it depends heavily on the case.
Before taking a case, most patent attorneys will conduct a detailed analysis. One of the central tools in that process is a claim chart.
A claim chart breaks down the language of a patent claim and compares it directly to the accused product or process. This is done element by element to determine whether there is a potential infringement.
This type of analysis requires time and expertise, which is why many firms charge an upfront fee for this initial evaluation.
After that stage, some firms may offer a hybrid arrangement, combining upfront fees with a contingency component. In particularly strong cases, a full contingency model may be possible, but those situations are relatively rare.
Most firms want to see clear, compelling evidence of infringement and potential damages before taking on that level of risk.
For businesses considering litigation, it’s important to plan for some upfront investment as part of building a credible case.
Political Slogans and Jingles
Returning to trademarks, another question that arises is whether political slogans or jingles can be protected.
In general, the answer is yes, provided certain conditions are met.
The same core requirements apply. The slogan must be original, you must have clear ownership, and it must be used in commerce.
Political campaigns often fall into categories related to education, advocacy, or promotion, which can support trademark use.
However, ownership is critical.
You cannot take an existing slogan, make minor changes, and claim it as your own. That approach typically leads to disputes and potential legal challenges.
If you’re seeking protection, the safest path is to develop something original and use it consistently over time. That’s what builds enforceable rights.
Final Thoughts on Sound Marks
Coming back to sound marks, it’s worth emphasizing just how high the bar is.
Yes, it’s possible to register a sequence of tones or a distinctive audio cue. But success depends on whether you can show that the public associates that sound with your brand.
That level of recognition takes time, exposure, and sustained use.
It also requires strong supporting evidence, surveys, expert analysis, and data demonstrating consumer perception.
For most businesses, this isn’t an early-stage strategy. It’s something to consider much later, after the brand has already achieved a meaningful level of recognition.
In that sense, sound marks are more of a long-term goal than a starting point.
The Big Picture
If you step back and look across all of these topics, trademarks, patents, enforcement, and litigation, a consistent theme emerges.
Proof matters.
Not just ideas. Not just intentions. Proof.
Proof that consumers recognize your brand. Proof that you created something first. Proof that your rights apply in a particular jurisdiction.
The strength of your position depends on the strength of your evidence.
You can have a great idea or a compelling brand, but without proof, your ability to protect and enforce those rights is limited.
Once that proof is established, however, everything changes.
Your rights become tangible. You gain the ability to enforce them, to protect your position, and to build real value around what you’ve created.
And ultimately, that’s where intellectual property becomes most powerful, not just as an idea, but as an asset.
