U.S. Trademark FAQs

A high level overview of U.S. trademark law.

Updated this week

What are trademarks?

Trademarks are words, designs, slogans, sounds, or symbols that identify and distinguish a specific product brand, such as a name for photocopiers or a logo for soft drinks. Service marks identify service brands, like a name for fast food or a symbol for package delivery. Both are often referred to simply as "marks." Collective marks indicate membership in an organization or goods from its members, while certification marks verify qualities like regional origin or product standards. Trademarks extend beyond names to include logos, slogans, packaging, product shapes, colors, sounds, smells, and even website aesthetics if they signal a business's source.

Why do trademarks matter in business?

A successful business or product name, like IBM or Google, contributes significantly to its value by identifying the business, aiding customer discovery, and fostering loyalty. Trademarks convey that products or services come from a specific company, and using one in the marketplace immediately subjects it to trademark law, which determines rights in disputes. Ignoring trademark law can lead to conflicts, as competitors may copy marks to attract customers.

What is trademark law, and why is it important?

Trademark law consists of principles from federal and state statutes, unfair competition laws, and court decisions that resolve disputes over identifiers for goods and services. It protects against unethical practices like copying marks that could confuse customers. Understanding it helps businesses choose and use marks without legal issues and address conflicts if they arise.

What are the basic principles of trademark law?

The first user of a mark in commerce owns it against later users. To qualify as a trademark, a mark must be inherently distinctive or acquire distinctiveness through use (secondary meaning). Owners can sue to stop uses causing customer confusion. Stronger marks receive broader protection. Courts typically order infringers to stop use, and deliberate copying of famous or registered marks may lead to damages. Avoid marks similar to national brands, federally registered marks (unless for unrelated products), or those piggybacking on well-known marks. For domain names, similarity to existing marks risks infringement, dilution, or cybersquatting claims.

What distinguishes strong marks from weak marks?

Strong marks are protectable because they are distinctive: coined words (like Polaroid), arbitrary terms (like Apple for computers), or suggestive terms (like Roach Motel). They are inherently distinctive and memorable. Weak marks describe qualities, ingredients, or characteristics (like Healthy Favorites or Chap Stick) and are not protectable unless they acquire secondary meaning through extensive sales and advertising, associating them with a single source.

How is trademark ownership determined?

Ownership goes to the first to use the mark in commerce (actual use on products or in service marketing) or the first to file an intent-to-use application with the U.S. Patent and Trademark Office (PTO), provided actual use follows. Multiple businesses can own the same mark if no customer confusion arises, such as for unrelated products or in different regions. If dual users conflict (e.g., one expands territory), courts consider factors like knowledge of prior use, federal registration timing, and initial marketing breadth. Internet use may reduce dual ownership viability due to national reach.

What role does customer confusion play in trademark law?

Most disputes hinge on whether simultaneous use likely confuses customers about product or service origins. Confusion can stem from similarity in sound, appearance, or meaning, even if marks aren't identical. Weaker marks allow more variations without confusion. Exact matches on unrelated goods (e.g., Delta for faucets and airlines) rarely confuse. Related products marketed similarly increase confusion risk.

What special protections exist for famous marks?

Famous marks are protected against dilution, which lessens their distinctiveness or tarnishes their reputation, even without customer confusion. Dilution includes blurring (reducing uniqueness) or tarnishment (harming quality perception). Federal law prohibits dilution without proving confusion, competition, or injury, with exceptions for parody or commentary.

How does trademark law enforce protections?

The system is self-policing; owners must act against infringers. Disputes are resolved through negotiations, PTO proceedings, arbitrations (for domain names), or federal lawsuits claiming infringement. Lawsuits seek injunctions to stop use and damages for harm. Most settle after initial rulings; litigation is costly, emphasizing business-focused resolutions like cease-and-desist letters.

What is the role of federal trademark registration?

Registration with the PTO enhances protection but isn't required for rights, which arise from use. Unregistered marks can still prevent confusing uses. Registration provides presumptions of ownership and validity, aiding lawsuits.

What is the Principal Register?

The PTO's primary list for registered marks. To qualify, marks must be in interstate or international commerce, distinctive, not confusingly similar to existing marks, and not off-limits (e.g., deceptive, using "U.S." improperly, surnames or geographies without secondary meaning, or single-issue artistic titles). Benefits include nationwide exclusivity (except prior users), notice via ® symbol, incontestability after five years of continuous use, and presumptions of ownership in court.

What is the Supplemental Register?

For non-distinctive marks ineligible for the Principal Register. It provides notice to searchers, allows ® use, and eases Principal Register transfer after five years of use (gaining distinctiveness). It offers limited court benefits but deters potential users.

What are state trademark registers?

States maintain registers for marks used within the state, providing notice and modest benefits like statewide priority claims. They complement federal registration but apply only locally.

Are all business names trademarks?

No. Trade names are formal business identifiers for banking, billing, and legal purposes (e.g., corporate names like Time, Inc., or fictitious names like Le Petite Cafe). Trademarks are names used to market goods or services. Small businesses often use trade names as trademarks (e.g., on signs), but registration as a trade name doesn't grant trademark rights.

What are trade name formalities?

Businesses must register trade names with state or local agencies to track ownership and screen similarities. Corporations register with state officials (e.g., secretary of state), ensuring names indicate corporate status and aren't misleading. Fictitious names (aliases) require filing certificates, often with county clerks, and sometimes newspaper publication for creditor notice. Applies mainly to sole proprietorships and partnerships; corporations use if operating under non-corporate names.

What is the relationship between trade names and trademarks?

Trade names become trademarks when creating commercial impressions (e.g., shortened versions with designs). Full trade names with addresses act as identifiers, not marks. Registering a trade name doesn't prevent conflicts if it's already a trademark elsewhere; marketing use risks infringement. Search for trademark and domain name conflicts before using trade names commercially.

What is trade dress and how does it relate to product designs?

Trade dress is a product's or service's total image via features like shape, color, texture, graphics, or sales techniques (e.g., restaurant decor, vodka bottle shapes). Product design, a subset, covers appearance (e.g., clothing lines). Both qualify as marks if distinctive and nonfunctional.

How is distinctiveness determined for trade dress?

Inherently distinctive if unique (e.g., restaurant with neon stripes and umbrellas). Otherwise, acquires distinctiveness via secondary meaning (public association through sales/advertising). Single colors or product designs aren't inherently distinctive and require secondary meaning.

Can trade dress be registered and protected?

Distinctive trade dress can be PTO-registered for extra protection but is enforceable unregistered if meeting criteria. Infringement requires confusion likelihood; similar appearances without confusion (e.g., prominent company names) may not infringe. Functional features aren't protected (e.g., indicators of use). Novel functional designs may qualify for patents. Trade dress can dilute famous marks if blurring or tarnishing.

What are the sources of trademark law?

Federal law provides registration, prohibits false advertising, infringement, dilution, and cybersquatting. State laws include antidilution, registration, dispute resolution, and unfair competition prohibitions. Common law from court decisions protects distinctive marks against confusing uses, even unregistered.

How does trademark differ from copyright?

Trademark identifies product/service sources and protects names, slogans, short phrases. Copyright protects original expression (e.g., books, art, music, software) for the creator's life plus 70 years, not ideas. Overlap occurs in logos, packaging, websites: trademark covers distinctive identifiers; copyright covers additional text/artwork.

How does trademark differ from patent?

Patents grant monopolies on inventions: utility patents (20 years from filing) for functional machines/processes/items if novel/nonobvious; design patents (14 years) for ornamental designs. Trademarks protect nonfunctional identifiers; overlap possible for ornamental designs serving as marks.
