Can I Trademark 6 7? — What the Phrase Means and How to Protect It

This post is about Can I Trademark 6 7?

Introduction to Can I Trademark 6 7?

If you’ve seen or heard people say “6 7” online, you’re not alone. The phrase has exploded across TikTok, Instagram, and other platforms — but what does it mean? And more importantly, can you trademark “6 7” if you want to turn it into a brand?

As a trademark attorney, I often get questions like this: Can I trademark a short phrase, number, or slang term that’s trending?The answer depends on how you use it and whether it functions as a brand identifier rather than just decoration or slang.

1. What Does “6 7” Mean Nowadays?

“6 7” (sometimes written as “67” or “six seven”) has become a viral, meme-driven expression among Gen Z and Gen Alpha users.

While it started as an obscure internet sound, its meaning has evolved — or, perhaps more accurately, refused to have a fixed meaning.

Here’s what it typically refers to in 2025:

• Meme origin: The phrase gained popularity after the song “Doot Doot (6 7)” went viral on TikTok.

• Height reference: NBA player LaMelo Ball, who stands 6′7″, is sometimes linked to the meme, adding a tongue-in-cheek “tall guy” association.

• Absurdist humor: According to VICE, “6 7” fits into the “brain-rot” meme category — random, meaningless humor that’s funny because it makes no sense.

• Mild reaction slang: Some people use “6 7” as a playful, neutral reaction — similar to saying “mid” or “eh.”

In short, “6 7” doesn’t have one set definition. It’s a flexible cultural reference used for comedic effect, which makes it both distinctive and potentially tricky from a trademark standpoint.

2. When You Can Trademark 6 7

You can trademark “6 7” if it is used as a source identifier — meaning it tells consumers where your goods or services come from. For example:

• “6 7 Studios” — if you run a creative agency or music label.

• “6 7 Apparel” — if you sell a streetwear line.

• “6 7 Media” — if you operate a podcast or entertainment platform.

If you use “6 7” as part of your brand name or logo, and not just decoration, it can qualify for trademark protection.

3. When You Can’t Trademark 6 7

The U.S. Patent and Trademark Office (USPTO) will refuse registration if the phrase doesn’t function as a trademark. Common reasons for rejection include:

• It’s just a meme or phrase everyone uses.If “6 7” is being used widely online as slang or a meme, the USPTO might find that it lacks distinctiveness.

• It’s merely ornamental.If you print “6 7” across the front of a T-shirt as decoration, that doesn’t count as trademark use.However, if “6 7” appears on the label, tag, or packaging, that does support trademark use.

• It’s descriptive or generic.If your use of “6 7” describes something about the product (for example, a model number, size, or version), it may not qualify for protection.

4. How to Strengthen a “6 7” Trademark Application

Here are ways to improve your odds of success:

1. Create a full brand identity.Use “6 7” in combination with a logo, tagline, or design — something that distinguishes it from casual slang.

2. Use it in commerce. You must sell a product or service under that name (or show intent to do so). The USPTO requires proof of use, like a website, label, or marketing material.

3. Choose the right class.For example:

   • Clothing → Class 025

   • Entertainment → Class 041

   • Online services → Class 042

4. File early. Meme phrases can go viral and fade fast — or worse, someone else could file before you. An early application gives you priority rights.

Work with an experienced trademark attorney.A professional search and filing can help avoid refusals, such as “failure to function” or “merely ornamental” issues.

5. Is It Smart to Trademark a Viral Phrase Like 6 7?

Maybe — if you’re turning it into a real brand.If you plan to build a business, clothing line, or creative project around “6 7,” then securing trademark rights could be a strong strategic move.

But if you’re simply trying to “own” a viral meme that’s widely used online, the USPTO will likely reject the application because phrases in common use are considered public domain expressions.

In that case, the phrase belongs to culture — not one company.

6. Bottom Line: Can I Trademark 6 7?

Yes, if you’re using it as a brand name, logo, or identifier for goods or services. No, if it’s just a meme, slogan, or decorative phrase.

The key is distinctiveness — the ability of “6 7” to tell consumers that your product comes from you, not just reference an internet trend.

FAQ: Trademarking “6 7”

Can I trademark a meme?

Usually not. Memes and viral phrases are considered part of public culture and lack the distinctiveness required for trademark protection. However, if you use a meme phrase as a business name or in a logo, it may qualify.

Can I trademark slang?

Yes, but only if it functions as a brand identifier. The USPTO will reject slang that’s widely used by the public with no connection to your business.

Can I trademark numbers or number combinations?

Yes. Many brands use numbers, such as “7-Eleven” or “23andMe.” The key is showing that the numbers represent your brand and are not generic or descriptive.

What class should I use for 6 7?

It depends on your business. Clothing brands usually fall under Class 025, entertainment or music under Class 041, and online media or tech services under Class 042.

What if someone else tries to trademark 6 7?

If another person files for a similar mark, your prior use can help you oppose the application or claim rights. Filing early is the best way to secure your brand.
