Trademark Classes Explained (Nice Classification)
When you file a trademark application, you must identify the specific class or classes that cover your goods or services. The classification system used worldwide is the Nice Classification, an international system established by the Nice Agreement (1957) and administered by the World Intellectual Property Organization (WIPO). The system currently divides all goods and services into 45 classes — 34 classes for goods (physical products) and 11 classes for services. Selecting the correct class is critically important because your trademark registration only protects your mark in connection with the goods and services identified in the registration.
Why Classification Matters
Trademark rights are not absolute — they are tied to specific goods and services. Two different companies can own identical trademarks as long as their goods and services do not overlap in a way that would cause consumer confusion. Delta Airlines and Delta Faucets coexist because airline services and plumbing fixtures are unrelated in the minds of consumers. The classification system provides the framework for defining the scope of your trademark rights. Filing in the wrong class can result in either too narrow a registration (leaving gaps in protection) or an office action from the USPTO requiring amendment.
Goods Classes (Classes 1-34)
The goods classes cover physical products. Some of the most commonly used classes for trademark applicants include Class 9 (computers, software, electronics, mobile apps, and downloadable digital content), Class 14 (jewelry, watches, and precious metals), Class 16 (paper goods, printed materials, and stationery), Class 18 (leather goods, luggage, bags, and umbrellas), Class 21 (household utensils, kitchen containers, and cleaning items), Class 25 (clothing, footwear, and headwear — one of the most heavily filed classes), Class 28 (games, toys, and sporting goods), Class 29 (processed foods including meat, dairy, and preserved fruits and vegetables), Class 30 (staple foods including coffee, tea, flour, bread, and confectionery), Class 32 (non-alcoholic beverages and beer), and Class 33 (alcoholic beverages except beer).
Services Classes (Classes 35-45)
The services classes cover commercial activities rather than physical products. Commonly used services classes include Class 35 (advertising, business management, retail services, and online retail — critical for e-commerce businesses), Class 36 (insurance and financial services), Class 38 (telecommunications), Class 41 (education, entertainment, and sporting activities — commonly used by coaches, content creators, and fitness professionals), Class 42 (scientific and technological services, software as a service, and computer programming), Class 43 (restaurant, catering, and hotel services), Class 44 (medical, veterinary, and beauty services), and Class 45 (legal, security, and personal services).
Filing in Multiple Classes
Many businesses need protection in more than one class. A clothing brand that also operates retail stores might file in Class 25 (clothing) and Class 35 (retail store services). A software company that provides both downloadable software and cloud-based services might file in Class 9 (downloadable software) and Class 42 (SaaS). Each additional class requires a separate filing fee ($250 or $350 per class depending on the application type) and a separate specimen of use. Multi-class applications are more complex but provide broader protection. Our multi-mark packages are designed to accommodate clients who need registration across multiple classes.
Common Classification Mistakes
The most common mistake is selecting a class based on the class heading rather than the detailed descriptions of goods and services within each class. The class headings are general summaries — inclusion in a class is determined by the specific goods or services, not the heading. Another common mistake is filing in too few classes, leaving gaps in protection that competitors can exploit. A third mistake is drafting an overly broad identification of goods and services that does not match your actual use, which can create problems when you need to provide specimens of use. A trademark attorney can help you identify the correct classes, draft precise identifications, and develop a filing strategy that provides comprehensive protection without unnecessary expense.
Frequently Asked Questions
How do I know which trademark class to file in?
Start by describing your goods or services as specifically as possible. Then search the USPTO's Trademark ID Manual at idm-tmng.uspto.gov to find pre-approved descriptions that match. If you are unsure, a trademark attorney can help you identify the correct classes and draft the identification of goods and services.
How much does each additional class cost?
Each additional class adds $250 (TEAS Plus) or $350 (TEAS Standard) to the USPTO filing fee. Our flat-fee packages include the attorney's work for the classes covered. Multi-mark and multi-class strategies are among the most common topics we discuss during initial consultations.
Can I add classes to an existing registration?
No. Once a registration is issued, you cannot add new classes to it. If you need protection in additional classes, you must file a new application. This is why getting the classification right at the outset is important — and why a trademark attorney's guidance is valuable during the application phase.
What if my product fits in more than one class?
This is common. A single product can involve multiple classes if it encompasses different types of goods or services. For example, a fitness app might require Class 9 (downloadable software) and Class 42 (SaaS) and Class 41 (fitness instruction services). File in all relevant classes to ensure complete protection.
