Direct Answer: If you are building a business, launching a product, or refreshing your brand, one of the first questions you may ask is: what can be trademarked? Trademarks are powerful because they help customers recognize where goods or services come from. A strong mark can protect a brand name, logo, slogan, product look, or even certain non-traditional brand identifiers when they are distinctive and used in commerce. This blog post explains the main categories of trademarkable material, what cannot be protected, and how Minnesota businesses can think about protecting their brands.

1. Core Eligibility Criteria for Trademarks
Before filing a trademark application, a proposed mark should meet two basic requirements. First, it must identify the source of a product or service, meaning consumers should be able to connect the mark with a specific business rather than viewing it as a simple product description. Second, the mark must be used in commerce, or the applicant must file an intent-to-use application showing a genuine plan to use the mark commercially. These requirements help ensure that trademark protection is reserved for brand identifiers that actually function in the marketplace.
2. What Can Be Trademarked (Categories & Elements)
When exploring what can be trademarked, it is important to know that trademarks can take many forms and are not limited to company names. Word marks protect names, product titles, brand names, and acronyms. Logos and symbols protect visual designs such as emblems, stylized artwork, and recognizable brand icons. Slogans and taglines may also qualify when they are used to reinforce brand identity and point consumers back to a particular source. Trade dress can protect the overall look and feel of packaging or product presentation, while non-traditional marks may include colors, sounds, scents, shapes, or motions, as long as they are distinctive and not functional. Understanding these categories is essential for anyone researching what can be trademarked to protect their unique brand identity.
3. What Cannot Be Trademarked
While understanding what can be trademarked is important, it is equally vital to know that not every word, design, or product feature can become a trademark. Generic terms are not protectable because they name the product or service itself, such as trying to register “coffee” for a café. Functional features are also excluded from what can be trademarked because trademark law cannot be used to control features that are essential to how a product works or how it is made. Descriptive phrases may face rejection unless the owner can show that consumers have come to associate the phrase with a single source. Deceptive or misleading identifiers, as well as official government flags, seals, and insignia, are also generally unavailable for trademark protection.
4. Levels of Trademark Distinctiveness
When evaluating what can be trademarked, trademark strength depends heavily on distinctiveness. The strongest marks are fanciful marks, which are invented words with no prior meaning, and arbitrary marks, which use real words in unrelated contexts. Suggestive marks are also strong because they hint at a quality or characteristic without directly describing it. Descriptive marks are weaker and usually require proof of secondary meaning before registration. At the bottom of the spectrum of what can be trademarked are generic terms, which cannot be registered because they identify the entire category of goods or services instead of one brand.
5. Minnesota-Based Trademark Examples
Minnesota offers plenty of recognizable examples of trademark protection in action. Companies such as 3M, Best Buy, Caribou Coffee, and Target have built strong brand identities through names, logos, and other identifying elements. The Target bullseye, for example, functions as a visual source identifier separate from the company name itself. Local breweries and consumer brands may also rely on packaging, label designs, and distinctive product presentation to separate themselves in a crowded market. For businesses operating only within Minnesota, state trademark registration may be useful, while companies selling across state lines often benefit from federal registration with the USPTO.
6. Frequently Asked Questions
What is the difference between a trademark, copyright, and patent?
A trademark protects brand identifiers such as names, logos, and slogans. Copyright protects original creative works, including books, photographs, songs, artwork, and software code. Patents protect inventions, functional systems, processes, and certain chemical compositions. In short, trademarks protect how customers recognize a brand, while copyrights and patents protect different kinds of creative or technical property.
Can I trademark a phrase or slogan used on t-shirts?
When determining what can be trademarked, a phrase used on a t-shirt may qualify only if it functions as a brand identifier. If the wording is displayed merely as decoration across the front of the shirt, the USPTO may treat it as ornamental rather than proper trademark use. For those researching what can be trademarked, placement on hangtags, neck labels, product packaging, or online store branding can help show that the phrase genuinely identifies the source of the goods.
Do I need to register federally, or is state registration enough?
State registration can be helpful for a business that operates only within Minnesota, but federal registration through the USPTO generally provides broader protection. A federal trademark registration can create nationwide rights, establish priority across all 50 states, and place the mark in the federal trademark database, which can discourage others from adopting confusingly similar marks.
How long does a trademark registration last?
A federal trademark registration can last indefinitely if the owner keeps using the mark in commerce and files the required maintenance documents on time. Unlike some forms of intellectual property, trademark protection depends on continued use and proper upkeep.
7. Protect Your Brand with Twin Cities Trademarks
Choosing the right trademark strategy can make a major difference in how well a business protects its identity and understands what can be trademarked.
From clearance searches to filing strategy, trademark protection requires careful attention to distinctiveness, proper use, and the scope of registration. Businesses in Minneapolis, St. Paul, and throughout the upper Midwest can benefit from reviewing their names, logos, slogans, and packaging to evaluate what can be trademarked before investing heavily in a brand launch.
In conclusion, almost any distinctive source identifier can potentially be trademarked, but knowing what can be trademarked ensures that the strongest protection belongs to marks that clearly distinguish one business from another.
