Trademark Infringement: What to Do If Another Business Uses Your Brand Name

Rosenthal IP LAW

Say you run a coffee shop called "Morning Ritual," and then a new café across town opens up as "Morning Rituals." Customers start mixing the two up online, tagging the wrong shop in reviews, showing up at the wrong location for a promotion you never ran. That mix-up isn't just annoying; it's the exact kind of consumer confusion trademark law exists to prevent. The question is what to actually do about it, and that depends on getting a few things right before you pick up the phone.


Step One: Make Sure It's Actually Infringement


Not every similar name is a legal problem. Before doing anything else, it's worth asking:
Does the other mark sound, look, or read similarly to yours? Is it being used for the same or related goods and services? Would a typical customer plausibly confuse the two? If those answers point toward "yes," you likely have a legitimate case. If the businesses operate in unrelated industries, or serve genuinely separate markets, there may be no infringement at all, and pursuing it burns time and legal fees for nothing.


Build Your Record First


Once you're confident it's a real conflict, start collecting proof before reaching out: screenshots of their website, social posts, packaging, or ads, etc. Make sure you record the date you captured the evidence and save it. If this ends up going further than a polite email, you'll want that record intact. (If you think this might go to court, an attorney should forensically capture this information.)


The Cease-and-Desist Letter Comes Next 


This is the standard opening move in nearly every trademark dispute. A good cease-and-desist letter identifies your registered mark, explains specifically why the other party's use creates a problem, and requests that they stop, typically within a set timeframe. Keep the tone firm but professional rather than combative. It's entirely possible the other business had no idea your mark existed when they picked their name, and a measured letter resolves more disputes than an aggressive one. Attorneys generally draft these rather than business owners doing it solo, mostly because getting the legal language and scope right matters if the letter ends up as evidence later. 


If the Letter Doesn't Land


Sometimes it works. Sometimes it's ignored entirely. When that happens, litigation becomes the real option. To win a trademark infringement suit, you typically need to establish three things: that you hold a valid registered mark or are otherwise the Senior User (i.e., have earlier rights in the trademark than the other party), that the other party is using an identical or confusingly similar mark on similar goods or services, and that the use is actually causing confusion or diluting your brand’s distinctiveness.


Courts don’t take a plaintiff’s word for that confusion, either. They apply structured, multi-factor tests to evaluate it. The Second Circuit's approach, first laid out in
Polaroid Corp. v. Polarad Electronics Corp., 287 F.2d 492 (2d Cir. 1961), weighs things like the strength of your mark, how similar the two marks actually are, how close the products or services sit to each other, and any evidence of real-world confusion among customers. Most circuits apply some version of this multi-factor analysis, and while the specific factors shift slightly by jurisdiction, the underlying question stays the same everywhere: would a reasonable consumer actually be confused?


What Winning Actually Gets You


If a court sides with you, the most common outcome is an injunction, a binding order requiring the other business to stop using the mark. Depending on how the infringement happened and how deliberate it was, courts can also award financial damages covering lost profits and possibly legal costs, and in cases involving outright counterfeiting, criminal penalties can come into play too. 


Know When to Let It Go 


Worth remembering: some overlap genuinely isn't infringement. Comparative advertising and legitimate news reporting can qualify for fair use protection, and two businesses with similar names in clearly distinct markets sometimes just coexist without either side having a real claim against the other.


If you're staring down a name conflict and can't tell whether it's worth pursuing, that's exactly the kind of question worth getting a real answer to before spending money on a letter or a lawsuit.

I often hear a common refrain: “I've been using this name for years, and nobody’s said anything, so I’m probably fine.” I understand that logic. But eventually, I get a phone call from that same business owner, and it is rarely a happy one. Another situation companies face is where they wait too long to file an application to register their trademark, only to find out that another company (that started using the same or a similar trademark at a later date) already filed an application. Common Law Rights Only Get You So Far Using a trademark does grant what are known as common law trademark rights. The problem is that these rights are geographically limited; they only protect you in the specific market where you’ve been doing business, not across the entire country. A federal registration with the USPTO provides a presumption of nationwide priority, the right to use the ® symbol instead of just ™, and a much stronger position in case of a dispute. While waiting to register a trademark does not negate your common law rights, it does leave the door open for someone else to claim rights in that same or a similar trademark elsewhere. What This Actually Costs You Filing a federal trademark application costs a few hundred dollars per product or service. This is a small price compared to the expenses of a forced rebrand, which includes new signage, packaging, and marketing, as well as the awkward task of explaining the name change to existing customers. Additionally, legal expenses incurred from responding to cease-and-desist letters can turn into an expensive procrastination habit. There’s also a quieter cost that often goes unbudgeted: lost search rankings, decreased web traffic, and a weaker position when trying to address copycat issues online. An unregistered mark leaves you with far fewer tools for enforcement. Your Filing Date Is Your Friend Here’s an unexpected advantage: your legal priority is established on the day you file, not when you receive the registration certificate (which can take 12 months or more, given USPTO timelines). Filing locks in your position in line nationwide. Generally, everyone who files after you is already behind you, registration or no registration. Therefore, it’s legally counterproductive to say, “I’ll wait until things calm down.” Don’t Let “Later” Become “Too Late” If a trademark registration is on your to-do list alongside “organize the garage,” I recommend moving it to the top of your priority list. Filing early is cheaper, stronger, and considerably less dramatic than waiting.

Thinking about selling your business in the future? Whether that’s years down the line or just around the corner, it’s important to recognize that your intellectual property (IP) might be worth a lot more than you think. In fact, it’s one of the easiest things for business owners to undervalue. During the buyer’s due diligence process, IP often emerges as a key asset. What they find (or don’t find) can significantly influence the sale price. Understanding the Value of IP When people assess a business's worth, they often focus on revenue, customer lists, and physical assets. However, intellectual property should definitely be on that list, too. Think about it: a strong trademark, a solid copyright portfolio, a reliable patent, or a protected trade secret are all unique assets that a buyer can’t easily replicate. This uniqueness is what drives up the value of your business. A well-maintained IP portfolio not only demonstrates your business’s long-term potential but can also directly impact how much a buyer is willing to pay. On the flip side, if your IP is undocumented, unregistered, or unclear, it can seriously harm your business’s value. If buyers can’t verify your IP, they’re unlikely to pay for it, and in some cases, it could even derail the sale entirely. Navigating Ownership Complications One of the most common pitfalls for business owners comes right before a sale. Many assume that their business automatically owns everything it creates, like its branding and inventions. However, IP created by contractors, freelance developers, or even some employees is not guaranteed to be owned by the business unless it's clearly outlined in contracts. What Buyers Really Want During due diligence, buyers and their legal teams typically look for: Registered trademarks, patents, and copyrights that are current and properly filed. Proper and current use of trademarks. Written agreements that clearly assign IP created by contractors and employees to the business. A clear history of ownership of IP without any hidden disputes or litigation that could affect the ownership. Experts recommend that business owners start tightening up their IP documentation six to twelve months before putting their business on the market, rather than waiting until the last minute. The businesses that fare best during a sale are those that have treated their IP as a valuable asset, documented ownership clearly, and kept everything organized well in advance. A Little Preparation Goes a Long Way If you’re even slightly considering selling your IP in the coming years, now is a great time to review your IP portfolio. If patents are likely to be part of the sale down the road, it would be wise to consult a patent attorney to examine your assignment records and ownership chains before buyers start asking questions. Similarly, you should be using and protecting your trademarks properly, with clear ownership of the trademarks and their goodwill. Additionally, since copyrighted content, software, and creative assets are crucial for valuation, working with copyright law firms that understand how these assets are valued can make a big difference. Rosenthal IP LAW is here to help you set up a consultative service to protect and document your IP, ensuring it adds value to your business rather than becoming a question mark during a sale.
