Patent Attorney and Founder
Using Your Last Name as a Trademark
Let’s say you start a business and decide to use your last name. It feels personal. It feels honest. In many ways, it feels like the most natural choice you could make.
So the question comes up pretty quickly:
“Can I trademark it like Disney or Hershey?”
At first glance, it seems like a simple yes.
But in reality, the answer is no, at least not right away.
The United States Patent and Trademark Office has a rule called the surname refusal. It sounds technical, but the idea behind it is actually pretty straightforward.
The law doesn’t want one person to control a common last name. If that were allowed, it could block others from using their own name in business, even if they’ve done nothing wrong.
Think about how many people share the same last name. Now imagine one of them gets exclusive rights to it for a certain type of business. Everyone else with that name is suddenly at a disadvantage.
That’s why the rule exists.
But this isn’t the end of the story.
There is a way to move past the surname refusal. It just doesn’t happen overnight.
If you use your name consistently in business and build a reputation around it, you may be able to show what’s called acquired distinctiveness. This means your name has taken on a new meaning in the minds of customers. It’s no longer just a last name, it’s a brand.
That shift is important.
It’s the difference between someone seeing your name and thinking, “That’s a person,” versus thinking, “That’s a company I know.”
Reaching that point takes time and effort.
You’ll need to show things like:
- How long you’ve been using the name
- How widely your business operates
- Whether customers recognize your brand
- Sales figures or marketing reach
The stronger your presence, the better your chances.
It’s worth noting that even five years of use, which is often cited as a benchmark, isn’t always enough on its own. The quality of your use matters just as much as the length of time.
For example, a business that quietly operates in one small area may not build the same level of recognition as one that actively markets and grows its audience.
So it’s not just about waiting. It’s about building.
When you look at companies like Disney or Hershey, it’s easy to forget that those names didn’t start out as powerful brands. They became that way over time through consistent use, strong identity, and public recognition.
That’s the real takeaway.
Using your last name is fine. In fact, it can be a strong branding choice. But turning that name into a protected trademark takes patience and proof.
Global Patent Enforcement Challenges
Now let’s shift into something a bit more complex.
What happens when a company from another country, let’s say China, wants to enforce a patent in the United States?
At a high level, it might seem like a straightforward legal step. You have a patent, someone is infringing, so you enforce it.
But once you get into the details, it becomes clear that things are not that simple.
The first issue is that patent law is territorial. That means each country has its own system. A patent granted in one country does not automatically give you rights in another.
So if a Chinese company wants protection in the U.S., they need a U.S. patent. And if they want to enforce that patent, they have to do it under U.S. law.
That alone creates a learning curve.
Beyond that, there are practical challenges.
You need to work with a U.S.-based patent attorney. The courts require it, and the system is built around local legal expertise.
But hiring counsel is just the starting point.
You’re also dealing with differences in how legal systems operate.
Some countries handle patent disputes quickly. Others move slowly. Some offer strong enforcement tools, like quick injunctions that can stop a product from being sold. Others may require a longer process before any action is taken.
There are also differences in how damages are calculated. In some systems, damages may be substantial and act as a deterrent. In others, they may be more limited.
Customs enforcement is another factor. In certain countries, it’s possible to stop infringing products at the border. In others, that option may not be as effective.
Licensing practices can vary too. In some regions, licensing is a common way to resolve disputes. In others, companies may be more likely to fight it out in court.
Now flip the scenario.
A U.S. company wants to enforce a patent in Asia.
The same issues apply, just in reverse.
You’re entering a different system, often with different expectations, different timelines, and sometimes even different approaches to intellectual property as a whole.
It’s not just about the law, it’s about how that law is applied in practice.
That’s why local expertise matters so much.
You need someone who understands not just the rules, but how those rules play out in real cases.
Without that, it’s easy to make mistakes or miss opportunities.
So while international enforcement is possible, it’s rarely simple.
It requires planning, coordination, and a clear understanding of where you’re operating.
USPTO Crackdown on Foreign Trademark Filings
This brings us to a recent development that highlights how these systems are evolving.
The United States Patent and Trademark Office has taken action against a large number of trademark registrations tied to foreign filings, particularly those connected to China.
We’re talking about more than 40,000 registrations.
That number alone tells you something unusual was happening.
For a number of years, there were incentives in China that encouraged companies to file trademarks in the United States. This led to a surge in applications.
On the surface, that might seem like a normal part of global business.
But in practice, not all of those filings were handled properly.
There were cases where U.S. attorneys were listed on applications without actually being involved in the work. They weren’t reviewing the filings or guiding the process. Their names were simply being used to meet formal requirements.
That’s a serious issue.
Trademark filings are supposed to be accurate and properly reviewed. When that process breaks down, it creates problems for everyone.
The USPTO responded by tightening its rules.
Now, foreign applicants must be represented by legitimate U.S. counsel who are actively involved in the application.
This isn’t just a technical requirement. It’s about accountability.
Attorneys are expected to review the filings, ensure accuracy, and stand behind the work being submitted.
We’ve already seen the impact of this shift.
Some attorneys have faced disciplinary action. Certain applications have been rejected or canceled. Entire groups of registrations are being reviewed more closely.
It’s a correction process.
And while it may cause short-term disruption, it ultimately strengthens the system.
It helps ensure that trademarks are meaningful, properly filed, and fairly enforced.
When a Big Company Takes Your Idea
Now let’s look at a situation that feels more personal.
You’re working on research during your PhD. You develop a new method or technique. You present it at a conference. Maybe it gets published.
Then, sometime later, a large company files a patent that looks very similar to your work.
It’s frustrating. And it raises a serious question, what can you do about it?
The first step is documentation.
You need to show that you had the idea first. That means gathering anything that proves your timeline.
- Research papers
- Conference materials
- Emails and correspondence
- Drafts and notes
The more detailed your records, the stronger your position.
From there, you have a few possible paths.
One option is to pursue a case in federal court. This is often the most direct approach, but it can also be expensive and time-consuming.
Another option is to challenge the inventorship of the patent. This involves arguing that the listed inventor is incorrect and that the patent should reflect the true creator.
There’s also a specific process called a derivation proceeding.
This is designed for situations where one party claims that another party derived the invention from them.
However, timing is critical.
You typically have one year from the date the other party files their patent application to initiate this type of proceeding.
If you miss that window, your options may be limited.
There’s another important factor to consider.
When someone files a patent application, they must sign an oath stating that they are the true inventor. If that statement is knowingly false, it can be considered fraud.
That adds another layer to the situation.
Allegations of fraud can significantly change the dynamics of a case. They can increase pressure on the other party and may lead to faster resolution through settlement.
So while facing a large company can feel overwhelming, there are still tools available to protect your rights.
The key is acting quickly and having strong evidence to support your claim.
How Patent Litigation Fees Work
Let’s talk about costs, because this is where many people hesitate.
Patent litigation has a reputation for being expensive, and that reputation is well-earned.
So naturally, people ask whether attorneys handle these cases on a contingency basis.
The answer is yes, but usually not from the very beginning.
Most cases start with an evaluation phase.
A major part of that phase is something called claim charting.
This involves taking the claims from your patent and comparing them, element by element, to the accused product or process.
It’s a detailed analysis.
You’re asking a simple question: does the product meet every part of the claim?
If the answer is yes, you may have a strong case.
If not, the case may not hold up.
This step takes time and expertise, which is why it typically involves upfront costs.
Once the analysis is complete, the attorney can better assess the strength of the case.
At that point, different fee structures may come into play.
Some attorneys may offer contingency arrangements, where they are paid based on the outcome. Others may use a hybrid model, combining upfront fees with a success-based component.
It all depends on the level of risk and the potential value of the case.
So while contingency is possible, it usually comes after a careful review of the facts.
Trademarking Political Slogans and Jingles
Another question that comes up often is whether political slogans or jingles can be trademarked.
The answer is yes, but there are some limits.
First, the slogan or jingle must be original. You can’t claim something that someone else created.
Second, it must be used in a way that identifies the source of goods or services.
This is where many applications run into trouble.
If a slogan is simply a message or a phrase that people repeat, it may not qualify as a trademark. It needs to point back to a specific organization or campaign.
The process itself is similar to any other trademark application. You select the appropriate category and provide evidence of how the slogan or jingle is used.
But the key issue is always the same.
Does it function as a brand?
If it does, you may be able to protect it. If it doesn’t, it may remain in the public domain.
Sound Trademarks and Nontraditional Marks
Finally, let’s look at something a bit more unusual.
Sound trademarks.
These are trademarks based on audio rather than words or images.
A well-known example is the NBC chime, a short sequence of tones that people instantly recognize.
These types of marks are possible, but they come with higher requirements.
You need to show that the sound is closely tied to your brand in the minds of consumers.
That often means providing strong evidence, such as surveys, expert analysis, and market data.
It’s also more expensive.
By the time you account for research, expert input, and legal work, costs can easily reach $20,000 or more.
Because of that, sound trademarks are usually pursued later in a company’s life cycle.
They’re not a starting point.
They’re a way to deepen protection once a brand is already well established.
Key Takeaways
When you step back and look at all of this, a few patterns start to emerge.
Building a brand takes time, and legal protection tends to follow that growth.
Last names can become trademarks, but only after they gain recognition.
Patent enforcement depends heavily on where you’re operating and who’s guiding you.
If someone takes your idea, acting quickly and having solid documentation can make all the difference.
And while trademarks can extend beyond names and logos to include slogans and even sounds, each type comes with its own challenges.
None of this is instant, and none of it is automatic.
But with the right approach, it’s all manageable.
The key is understanding the process early, so you can make smarter decisions as your business grows.
