📌 Quick Summary
1-Sentence Answer
You and another business can legally use the same (or very similar) brand names or logos—as long as your products or services are completely unrelated and unlikely to cause customer confusion.
The Article Overview
This article explains when and why two companies can use identical or similar trademarks for different products and services, the legal logic behind it, what counts as “unrelated,” and what to do if you spot a brand twin out in the wild.
❓ Common Questions & Answers
Q1: Can two businesses have the same brand name?
A: Yes—if they sell unrelated goods or services (think “Delta” airlines vs. “Delta” faucets), both can legally use the same name without trademark infringement.
Q2: What does “unrelated” mean in trademark law?
A: “Unrelated” means the goods or services are so different that consumers wouldn’t expect them to come from the same company—like yogurt and tires!
Q3: What if two companies start using the same name in related fields?
A: That’s where trademark law steps in. If customer confusion is likely, it’s usually infringement and the later user must rebrand.
Q4: Can a big brand block all use of its name everywhere?
A: Not usually. Trademarks only cover the types of goods/services registered—not everything under the sun!
Q5: What should I do if I spot my brand name in another industry?
A: Consult a trademark attorney. If there’s no overlap or confusion, you’re probably both fine. If not, you may have a case.
📜 Step-by-Step Guide
Step 1: Identify your goods/services. What do you actually sell?
Step 2: Check if the “other” brand sells unrelated products/services (think: tires vs. yogurt).
Step 3: Analyze the likelihood of confusion—would a typical customer mix up your brands?
Step 4: Review trademark classes—each class covers specific goods/services.
Step 5: If still uncertain, get a legal opinion from a trademark attorney (preferably with flat fees and a sense of humor).
Step 6: If there’s overlap, consider sending a cease and desist—or negotiating a coexistence agreement.
📖 Historical Context
Trademark law has always balanced the need to protect brand identity with the realities of a crowded commercial world. In the early days, trademarks primarily protected merchants from direct competitors in the same city or trade. But as markets and media expanded, so did the risk of overlap. Enter the “likelihood of confusion” test—a legal way to ask, “Would a customer actually think these two brands are the same?”
One famous case involves “Delta”—a name used by both a major airline and a faucet manufacturer. Courts ruled no one would confuse a flight to Atlanta with a new showerhead. Over time, courts recognized that as long as products/services were unrelated, brand twins could coexist peacefully—often blissfully unaware of each other.
Today, with thousands of trademarks registered daily, duplicate names across unrelated fields are common. The law still asks: “Would a reasonable buyer actually be confused?” If not, the brands can go about their business—yogurt or tires, no problem.
🏢 Business Competition Examples
-
Delta Airlines vs. Delta Faucets
No one expects a plumbing supply company to fly them to Paris, so these brands happily coexist. -
Apple Computers vs. Apple Corps (The Beatles)
Computers and music were considered unrelated—until iTunes arrived, triggering a famous legal dispute. -
United Airlines vs. United Van Lines
Both offer “moving” services, but planes and moving trucks are distinct enough to allow both brands. -
Canon Cameras vs. Canon Printers
These share a name and an industry but are owned by the same company—showing that sometimes, expansion means you own both uses!
💬 Discussion Section
So, you’ve spotted your brand name on a completely different product. Should you panic, sue, or just laugh? In trademark law, not all name twins are a crisis. Trademarks only protect your brand in connection with specific goods or services. The key question: Would a reasonable customer think these brands are related?
If your bakery “Sunrise” finds a “Sunrise” car dealership in another state, it’s almost certain no one will assume both businesses are linked (unless your cinnamon rolls come with a free oil change). That’s why trademark registration involves picking classes for your goods/services—not claiming ownership of a word everywhere.
But what if your “Sunrise” bakery becomes so famous that everyone knows the name? Enter “famous mark” status. Brands like “Kodak” and “Nike” are protected more broadly, but most small businesses won’t reach that level—and that’s okay. Your focus should be on making sure no one in your industry, or related industries, causes confusion with your brand.
Where it gets tricky is when industries overlap, or when companies expand into new markets. Remember the “Apple” case: computers and music didn’t seem related—until they were! So, keep an eye out for expansion and always check with a trademark attorney if you spot a possible overlap.
Bottom line: You can share your brand name with an unrelated business. Just don’t sell yogurt and tires at the same shop—unless you’re aiming for legendary confusion.
⚖️ The Debate
Side 1: Brand Owners Deserve Broad Protection
Some argue that allowing brands to share names, even across unrelated industries, weakens brand value and can lead to future conflicts—especially if businesses later expand into new markets.
Side 2: Too Much Protection Stifles Commerce
Others say strict “one brand, one name” rules would exhaust all possible brand names and stifle new businesses. Trademark law’s focus on consumer confusion strikes the right balance—allowing creative overlap without chaos.

🔚 Wrap-Up Conclusion
Trademark law isn’t about claiming every possible use of your brand name—it’s about making sure your customers aren’t confused. Two businesses can absolutely share the same or similar names if their products and services are worlds apart. So unless your tire shop starts selling yogurt, you’re probably safe. For everything else, remember: when in doubt, talk to a trademark attorney who speaks both legalese and “plain English yogurt.”
