Why The MUSH™ Rejection Matters: A Wake-Up Call For Aspiring Brand Owners

If you’ve been to Costco recently, you might have seen the oat-based, ready-to-eat breakfast products from Mush Foods. They’re eye-catching, healthy, and gaining traction in the marketplace. But behind the scenes, there’s a trademark battle brewing—and it’s a powerful reminder of just how unforgiving the U.S. trademark system can be. Below, our friends Below, our friends from Trademark Lawyer Law Firm discuss why the brand Mush Foods was denied getting the trademark they were seeking.

In a recent decision from the Trademark Trial and Appeal Board (TTAB), the USPTO officially refused registration of the term “MUSH” as a trademark for “ready-to-eat cereals; breakfast cereals; all the foregoing made in whole or significant part of oats.” Why? Because they found the word to be generic.

Not merely descriptive. Not confusingly similar to something else. Generic. And that’s a death sentence for a trademark application.

Why Was “MUSH” Rejected?

The Board concluded that consumers primarily understand the word “mush” as a general term for a category of food—specifically, oat-based or porridge-style breakfast foods. They cited multiple dictionary definitions and real-world usage of the word, including recipes for “banana spice oatmeal mush” and historical references to mush as a common breakfast dish. In short, they determined that “MUSH” isn’t a brand—it’s a type of food. And you can’t trademark a food category.

Even though Mush Foods has used the term for years and their products are sold at major retailers, the Board said that’s not enough. The law doesn’t care how much money you’ve spent on branding or how successful your product is—if your trademark is generic, it doesn’t get federal protection.

This decision hit home for many who’ve actually seen the product in Costco. And like many consumers, they thought it was a brand name. But under U.S. trademark law, consumer recognition alone doesn’t always win the day. That’s why understanding what you can and cannot protect with a trademark is so important.

What’s The Lesson?

The first and most obvious takeaway: trademark law is unforgiving when it comes to generic terms. You can build a great product, get national distribution, and still lose your ability to lock down the name if the USPTO thinks it’s too generic.

Second, this case shows why strategy matters early. If Mush Foods had gone with a more distinctive brand name—something suggestive, arbitrary, or even fanciful—they might have avoided this entire issue. But now they’re fighting uphill, without a registration to back them up.

Finally, this highlights the danger of building a brand without understanding what the law protects. If you’re launching a new food product, cosmetic, app, or service, the name you choose matters. The wrong name could be unprotectable. The right name could be an asset you can defend for decades.

Don’t Assume. Ask.

If you’re not sure whether your brand name is protectable, don’t wait until your application is denied. Let a trademark litigation lawyer help you evaluate the strength of your trademark before you invest in packaging, advertising, or distribution.

And if you’re already in the market, but haven’t registered your name yet, now’s the time. A smart trademark strategy could save you from public rejections, costly rebranding, or even lawsuits down the line.

This case is a reminder that just because something sounds like a brand doesn’t mean the USPTO will treat it that way.
