Nice Classification 13th Edition: New Trademark Filing Rules from 1 Jan 2026
The Nice Classification 13th Edition took effect on 1 January 2026, and India's Trade Marks Office now validates new filings against it under Rule 21. Contact lenses move from Class 9 to Class 10, AI and SaaS descriptions need more precision, and applications using 12th Edition wording risk a Rule 22 examination report and 3–6 month delay.

Legal basis: Trade Marks Rules, 2017, Rule 21 (e-filing/classification validation), Rule 22 (formal examination), Rule 23 (multi-class applications), read with the Fourth Schedule to the Rules — Effective: 1 January 2026 (Nice Classification 13th Edition). Source: https://www.wipo.int/classifications/nice/en/. Last reviewed by CA Harun Raaj: September 2026.
Every trademark application filed in India since 1 January 2026 is checked against the 13th Edition of the Nice Classification, not the 12th. If your goods/services description still reads the way it did in 2025, the IP India e-filing portal or the examining officer will catch it — and the fix costs you time, not just money.
What Is the Nice Classification and Why It Just Changed
The Nice Agreement, to which India is a party, sorts all goods and services into 45 classes for trademark registration. India incorporates this system through the Fourth Schedule to the Trade Marks Rules, 2017, and every Form TM-A application must cite the correct class for the goods or services being protected.
The classification is revised periodically. The 13th Edition replaced the 12th Edition with effect from 1 January 2026, updating how new categories of technology services, healthcare goods, and digital business services are described and grouped.
What Actually Changed
Contact lenses moved from Class 9 to Class 10. Contact lenses and related products — lens care solutions, storage cases — now belong to Class 10 (medical, surgical, and dental apparatus) instead of Class 9 (scientific, optical, and electronic apparatus). Optical retail chains, pharmaceutical distributors, and e-commerce platforms listing healthcare goods must file new contact lens applications in Class 10.
AI service classification got more precise. The 13th Edition separates AI services by function rather than by technology label: providing artificial intelligence software sits in Class 42 (scientific and technological services), while AI-based commercial analytics and market research services sit in Class 35 (advertising and business services). Businesses building AI platforms must classify by what the service actually does for the client, not by the fact that it uses AI.
Bare "SaaS" descriptions no longer pass. Class 42 specifications that simply say "software as a service" are treated as incomplete. The 13th Edition requires function-specific wording — for example, "providing software as a service for accounting management" rather than just "SaaS."
Key point: Applications filed from 1 January 2026 that still use 12th Edition class descriptions — including Class 9 for contact lenses or bare "SaaS" wording — are flagged during Rule 22 formal examination, adding roughly 3–6 months to the registration timeline.
How an Illustrative Business Gets Caught Out
A Bengaluru-based optical retail chain filing a new trademark for its branded contact lens line in 2026 would have filed correctly in Class 9 under the 12th Edition. Filing the same application in Class 9 in 2026 triggers a formal examination report under Rule 22. Refiling in Class 10 adds 3–6 months to the registration timeline and additional professional fees on top of the original application cost.
How This Affects Your Application
Portal validation under Rule 21: The IP India e-filing portal checks submitted goods/services descriptions against the 13th Edition database at the point of filing. Descriptions carried over from older specifications may not validate cleanly.
Formal examination under Rule 22: The Trade Marks Registry verifies that goods/services sit in the correct class. A misclassified specification — such as contact lenses under Class 9 — draws an examination report requiring correction before the application can proceed.
Multi-class risk under Rule 23: In a multi-class application, each class must independently carry a compliant specification. A deficiency in even one class delays the entire application, including classes that were correctly specified. Where protection is needed across multiple categories, single-class filings reduce this cross-class exposure.
Steps to Comply
- Check descriptions against the 13th Edition using the WIPO Nice Classification database at https://www.wipo.int/classifications/nice/en/.
- Use the IP India portal's live classification search at ipindiaonline.gov.in rather than reusing an older specification.
- Reclassify contact lens products into Class 10 for any new application.
- Write function-specific SaaS descriptions in Class 42 instead of bare "software as a service."
- Review pending 2025 filings that still carry 12th Edition wording and consider a voluntary amendment before the Registry examines them.
Separately, the Controller General of Patents, Designs and Trade Marks published a Revised Draft Manual of Trade Marks Office Practice and Procedure on 21 August 2026, open for public comments within 15 days. It adds a chapter on well-known marks and updates opposition procedure and examination workflow guidance — relevant reading for anyone with a pending trademark matter.
Talk to Us Before You File
Getting the class specification right the first time avoids an avoidable examination report and the months it costs. If you're filing a new trademark application, adding classes at renewal, or hold a pending 2025 application with older classification wording, this is worth a proper review of your specific goods/services list before submission.

Frequently Asked Questions
Does the Nice Classification 13th Edition affect my existing trademark registration?
No. Existing registrations made under the 12th Edition or earlier remain valid as filed. The 13th Edition, effective 1 January 2026, applies to new applications and to renewal filings where new classes are being added.
My contact lens brand is already registered in Class 9 — do I need to refile?
Your existing Class 9 registration stays valid; you cannot reclassify a granted registration retroactively. However, any new mark or new application covering contact lenses filed from 1 January 2026 must be filed in Class 10 under the 13th Edition.
Will the IP India portal reject my application outright for using a 12th Edition description?
The portal may still accept the submission, but under Rule 22 formal examination the Registry examiner will flag the mismatch, which adds roughly 3–6 months to the registration timeline. Filing correctly under the 13th Edition from the start avoids this delay.
My startup runs an AI analytics platform — which Nice class applies?
It depends on the primary nature of the service under the 13th Edition: the AI software platform itself falls under Class 42, while AI-based commercial analytics or market research for third parties falls under Class 35. Many AI businesses need to file in both classes depending on what they actually offer clients.
Can I still describe my product as just 'software as a service' in Class 42?
No. The 13th Edition requires function-specific SaaS descriptions, such as 'providing software as a service for accounting management,' rather than a bare 'SaaS' specification, which now attracts an examination report.
What happens if one class in my multi-class application is misclassified under the 13th Edition?
Under Rule 23, each class in a multi-class application must independently carry a compliant specification. A deficiency in a single class — for example, contact lenses cited under Class 9 instead of Class 10 — delays the entire application, including classes that were correctly specified.
I filed my trademark application in 2025 under the 12th Edition — should I do anything now?
Review the goods/services description against the 13th Edition and consider a voluntary amendment before the Registry takes up formal examination under Rule 22, particularly if your goods fall in a category that changed class, such as contact lenses.
Where can I check the correct class for my goods or services under the 13th Edition?
Use the WIPO Nice Classification 13th Edition database at wipo.int/classifications/nice/en/, and cross-check using the IP India e-filing portal's live classification search rather than relying on an older specification list.
