Trademark class mistakes, such as choosing the wrong class, ignoring related classes, or using vague descriptions, can lead to objections, protection gaps, and additional filing costs. While many applicants focus on trademark registration, they often overlook class selection. The trademark class selection determines the scope of legal protection their registration provides.
India follows the Nice Classification (NCL) system, which divides goods and services into 45 trademark classes under Section 7 of the Trade Marks Act, 1999. Choosing the wrong class can leave key goods, services, or business activities unprotected.
This guide covers the most common trademark class mistakes, their consequences, and practical ways to avoid them.
Key Takeaways
- Match each class to your actual business activities, not to how the class name sounds.
- Always run a class-specific trademark search before filing to avoid objections and oppositions.
- Vague descriptions like “computer software” attract objections and weaken your protection.
- Outdated Nice Classification terms can trigger objections, so check your goods and services against the latest edition (NCL 13).
- Most businesses need more than one class, so review related classes and expansion plans before you file.
Top 11 Trademark Class Mistakes to Avoid
A trademark is only as strong as the classes it covers. These are the most common mistakes applicants make when selecting trademark classes for goods and services:
1. Confusing Goods and Services Classes
The Nice Classification divides trademarks into two broad categories:
- Classes 1–34 for goods
- Classes 35–45 for services
Many applicants file under the wrong category and end up providing protection for a product when they actually provide a service, or vice versa. For example, a SaaS company that files only in Class 9 protects downloadable software but may fail to protect its cloud-based services under Class 42.
Tip: Determine whether your business sells goods, provides services, or does both before selecting a class.
2. Skipping a Trademark Search
Some applicants choose the correct class but fail to check for similar trademarks already registered in that class. This can result in trademark oppositions, objections, delays, and wasted filing fees.
Tip: Conduct a class-specific trademark search on the IP India trademark database or use RegisterKaro’s free trademark availability search tool before submitting your application.
3. Using Vague or Generic Descriptions
Many applicants submit generic descriptions such as “computer software” or “consultancy services” without specifying the nature of their products or services. These frequently attract trademark objections and can weaken the scope of protection.
Tip: Clearly describe what you offer, who you serve, and the nature of the activity.
4. Choosing a Class Based on the Name
Many applicants assume a class is appropriate because its title sounds relevant to their business. However, trademark classes are based on the actual nature of the goods or services, not the class name.
For example, a clothing brand may correctly file in Class 25 for apparel but overlook Class 35 for online retail services. As a result, it may leave its e-commerce activities unprotected.
Tip: Always match your classes to your business activities and the Nice Classification using the IP India Search portal or RegisterKaro’s free trademark class search tool.
5. Keeping Overly Narrow Descriptions
Some applicants describe their goods or services so narrowly that they exclude related offerings within the same class. For example, a specification limited to “leather wallets” may not adequately cover travel bags, handbags, or other leather accessories sold under the same brand.
Tip: Cover the full range of goods or services you currently offer or realistically plan to offer.
6. Ignoring Related Trademark Classes
Many businesses protect only their primary product or service and overlook related classes that support their brand.
For example:
- A food brand in Class 30 may also need Class 32 and Class 43.
- A fitness business in Class 41 may also need Class 25 and 32.
Tip: Review your entire business model, not just your core offering, when selecting classes.
7. Using Outdated Nice Classification Terms
The Nice Classification is updated regularly. Using outdated descriptions or terminology can attract objections and complicate the examination process. For example, the 13th Edition of the Nice Classification reclassified key products based on their use and function:
- Eyewear products such as spectacles and contact lenses moved from Class 9 to Class 10.
- Electrically heated clothing moved from Class 11 to Class 25.
- Artificial Intelligence as a Service (AIaaS) is now recognized under Class 42.
Tip: Verify your goods and services against the latest Nice Classification (13th edition in 2026) before filing.
8. Avoiding Multi-Class Filing to Save Costs
To reduce filing costs, some applicants register their trademark in only one class even though they operate across multiple categories. This approach often creates gaps in protection and increases costs later if additional applications become necessary.
Tip: Evaluate all relevant classes before filing. Adding classes early is usually cheaper than correcting omissions later.
9. Ignoring Future Expansion Plans
Many applicants focus only on their current products or services and often forget or ignore planned expansion. For example, a clothing brand registered in Class 25 may later expand into bags and accessories covered by Class 18.
While businesses can file additional classes later, each new class requires a separate application, fresh government fees, and a full examination process. This takes additional time and creates a gap during which a competitor can register the same or similar mark in the new class and block expansion.
Tip: Consider your growth plans for the next few years and include classes that align with likely business expansion.
10. Overlooking International Filing Requirements
Although many countries follow the Nice Classification system, they may apply it differently. For instance, a specification accepted in India may require modification when filing in another jurisdiction.
Tip: Review local trademark requirements, such as local filing standards for class descriptions, before filing internationally or through the Madrid Protocol.
11. Filing Without Professional Review
Many applicants view class selection as an administrative step rather than a legal strategy. Without proper review, they may choose the wrong classes, miss related ones, or use inadequate specifications that weaken trademark protection.
Tip: Seek professional guidance during multi-class filing or when your business operates across diverse products and services.
How to Choose the Correct Trademark Class in India?
Choosing the correct trademark class requires careful planning and less guesswork. Follow these five steps to ensure your application covers all relevant business activities:
- List Your Goods and Services: Identify everything your business currently sells or offers, as well as any products or services you plan to launch in the near future.
- Match Each Item to the Right Class: Use the latest Nice Classification (NCL 13) and the TM class database to determine the appropriate class for each product or service.
- Review Related Classes: Consider adjacent trademark classes that may also apply to your business. For example, online sellers often need Class 35, while SaaS businesses may require both Class 9 and Class 42.
- Conduct a Trademark Search: Search the IP India trademark database in every relevant class to identify similar marks and avoid potential objections under Section 11.
- Use Clear Descriptions: Describe your business’s goods and services accurately and specifically. Avoid using vague or overly broad terms that may lead to examination objections.
Why Trademark Class Selection Matters?
The trademark class defines the scope of protection a brand receives. When you choose the correct class, you secure protection for the goods and services you actually offer and reduce the risk of objections during examination. The right class also strengthens your ability to act against infringers, and keeps room open for future expansion into related areas.
Choosing the wrong class creates legal, financial, and strategic setbacks:
- Application refusal or abandonment: Failure to resolve objections can result in refusal or abandonment, causing you to lose the filing fee.
- Additional filing costs: Refiling means paying government fees (₹4,500 per class for individuals, startups, and MSMEs, or ₹9,000 per class for other applicants) and professional charges again, increasing the overall cost of trademark registration.
- Weaker enforcement rights: A mismatch between your registration and business activities can weaken your position in infringement, opposition, or enforcement proceedings.
- Challenges during business expansion: Expanding into new products or services becomes more difficult if your trademark registration does not cover the relevant classes.
