What Is a Trademark and How to Register One

What Is a Trademark?

A trademark is any word, phrase, symbol, design, or combination thereof that identifies and distinguishes the source of goods or services. Trademarks serve as signals to consumers — they indicate origin, represent the reputation and goodwill of the brand behind them, and allow purchasers to make informed choices in the marketplace. The Nike swoosh, the McDonald's arches, and the Apple logo are among the most recognizable trademarks in the world, each immediately communicating a brand identity and the quality expectations associated with it.

Service marks are the equivalent of trademarks but apply to services rather than goods. Trade dress refers to the overall image and appearance of a product or business, including packaging, color schemes, and store layouts, that signals origin — the distinctive shape of a Coca-Cola bottle and the particular layout of an Apple store have both been recognized as protectable trade dress.

Trademark law serves both consumer protection and business interests. It prevents consumer confusion about who makes a product, and it protects the investment businesses make in building brand recognition and reputation. Unlike patents, trademarks do not expire as long as they continue to be used and renewed — the Levi's brand has been in use for over 150 years and continues to be protected.

Types of Marks and Distinctiveness

Not all words or symbols can be trademarked. The key requirement is distinctiveness — the mark's ability to function as an identifier of source. Marks are classified along a spectrum from most to least protectable. Fanciful marks are invented words with no meaning outside the brand — KODAK and XEROX are examples. These are the strongest marks because they have no meaning except as brand identifiers.

Arbitrary marks are real words applied to unrelated goods or services — APPLE for computers, AMAZON for an online retailer. Like fanciful marks, these are inherently distinctive and strongly protectable. Suggestive marks hint at a quality or characteristic of the product without directly describing it — NETFLIX for video streaming suggests something about its service but requires imagination to make the connection. These are also protectable without proof of acquired distinctiveness.

Descriptive marks directly describe a characteristic of the product — CREAMY for yogurt or COLD AND CREAMY for ice cream. These cannot be registered without proof that consumers have come to identify the mark with a particular source through extensive use, a quality known as secondary meaning or acquired distinctiveness. Generic terms — the common name for a product category — can never be trademarked. ASPIRIN and ESCALATOR were once brand names but became generic through widespread use, a process called genericide that trademark owners work hard to prevent.

How Trademark Rights Arise

In the United States, trademark rights arise through use in commerce — by actually using the mark in connection with goods or services in the marketplace, not merely by registration. Priority of rights generally goes to the first user of the mark in a given geographic area and category of goods or services. This is the common law trademark system, unique to the US compared to most other countries where registration determines priority.

However, federal registration through the USPTO dramatically expands these rights. Registration provides nationwide constructive notice, meaning that anyone who adopts a confusingly similar mark after registration is deemed to have known about the registered mark regardless of actual knowledge. It creates a presumption of the registrant's exclusive right to use the mark and enables the owner to prevent importation of infringing goods through US Customs.

The intent-to-use (ITU) application is a mechanism that allows applicants to reserve a mark before actual use begins, as long as bona fide intent to use it in commerce can be demonstrated. This is particularly useful for businesses planning product launches. The applicant has up to three years after filing to begin use and submit a statement of use, after which the registration is finalized.

The Federal Registration Process

Trademark registration begins with a clearance search — a thorough investigation of existing registered and unregistered marks to assess whether the proposed mark is available and unlikely to be confused with others. A professional search covers USPTO databases, state trademark registrations, common law uses (including company names and domain names), and international registrations. Skipping this step risks filing an application that will be rejected or a mark that will be challenged by existing users.

The application filed with the USPTO must include the mark, the goods or services it will be used with (described in one or more of 45 international classes), the date of first use in commerce, and a specimen showing use (or a statement of intent to use). The application goes through examination by a trademark examiner who checks for compliance with requirements and searches for conflicting marks. Office Actions citing problems — refusals, requirements for more information, or requests to clarify descriptions — are common and must be responded to within specified deadlines.

If approved, the application is published in the Official Gazette for a 30-day opposition period, during which any party who believes they would be damaged by registration can file an opposition. If no opposition is filed or any opposition is resolved in the applicant's favor, the mark proceeds to registration. Registration typically takes 8 to 12 months for straightforward applications, though contested applications can take considerably longer.

Maintaining and Protecting a Trademark

Once registered, trademark owners must actively maintain their marks. Between the 5th and 6th years after registration, a Declaration of Continued Use (Section 8 affidavit) must be filed along with a specimen showing current use. At 10 years and every 10 years thereafter, the owner must file a combined Declaration of Continued Use and Application for Renewal (Section 8 and 9). Failure to file these maintenance documents results in cancellation of the registration.

Trademark owners must also police their marks — monitoring for infringers and taking action when necessary. Courts have held that failing to enforce a trademark can result in abandonment of rights or weakening of the mark's distinctiveness. Trademark owners typically send cease-and-desist letters as a first step, followed by opposition or cancellation proceedings before the PTAB or federal litigation for more serious infringement.

The Lanham Act, which governs federal trademark law, provides remedies for infringement including injunctive relief, recovery of defendant's profits, actual damages, and attorney's fees in exceptional cases. Counterfeiting is treated especially severely and can result in enhanced damages and criminal penalties. Protecting trademark rights internationally requires registration in each country or through the Madrid Protocol, an international treaty that allows a single application to cover multiple member countries. International trademark strategy is essential for brands with global reach or ambitions.

Trademarks vs. Other Intellectual Property

Trademarks differ from patents and copyrights in important ways. Patents protect technical inventions for a limited term, then expire. Copyrights protect creative expression for the author's life plus 70 years. Trademarks, by contrast, can last indefinitely as long as they are used and renewed — making them potentially the most enduring form of intellectual property protection.

A brand may simultaneously benefit from all three types of protection. A new consumer electronics product might be protected by utility patents on its technology, design patents on its appearance, copyright on its software and marketing materials, and trademarks on its name and logo. Understanding how these layers of protection overlap and complement each other allows businesses to build comprehensive IP strategies that protect their innovations, creative assets, and brand identity.

Trade secrets — discussed in a separate guide — represent another layer of protection for confidential business information. Together, these forms of intellectual property constitute the legal framework that encourages innovation and creative production by ensuring that creators and inventors can benefit from their work before it becomes available to the world at large.
