A trademark system is supposed to describe the economy as it actually trades, yet for years South African filings have squeezed twenty-first-century products into categories drawn for an older market. From 1 January 2026, that lag narrowed: South Africa adopted the 13th edition of the Nice Classification, the international scheme that sorts goods and services into the classes every trademark application must choose from.

The headline change is small in wording and large in signal. “AI-as-a-Service” now has a recognised home in Class 42, the class that already covers software and technology services. The taxonomy has caught up with the product roadmap.

Classification: Why the Right Box Matters

The Nice Classification is the plumbing of brand protection. Choose the wrong class and a mark may be registered against goods the business does not sell, leaving the products it does sell exposed. The 13th edition, adopted in South Africa from 1 January 2026, reshuffles several long-standing entries: goods such as essential oils are reclassified, and eyeglasses move to Class 10, the medical-devices class.

These are not cosmetic edits. A filer who copies last year’s specification onto this year’s application risks landing in a class that no longer fits, and a misfiled mark is weak precisely where it needs to be strong. For brand owners and their advisers, the update is a prompt to re-read the specification rather than recycle it.

Takeaway: the value of a trademark is decided by the class it sits in, not the name on the certificate.

Class 42: Naming the AI Economy

The addition of AI-as-a-Service to Class 42 is the change that speaks to where the market is heading. Until a product category is named in the classification, applicants must describe it in workarounds, and workarounds invite inconsistency and disputes. A recognised term gives filers a settled vocabulary and examiners a settled reference.

For South African operators, the practical effect is timing. A Johannesburg startup selling a machine-learning model on subscription, or a Cape Town firm packaging analytics as a hosted service, can now protect the brand under a label that matches how it sells. As more of the local technology sector moves from selling licences to selling intelligence delivered as a service, a class that recognises that model lowers the cost of defending it.

The benefit compounds beyond a single filing. A settled term reduces the room for an examiner to question the description, narrows the grounds on which a competitor can challenge the scope, and makes it easier to extend the same brand into related services later. For a young firm whose chief asset is its name, that clarity is worth claiming early rather than retrofitting after a dispute.

Takeaway: when the classification names a product, the market has a cleaner way to own its brand.

Maintenance: An Audit Worth Running

The quieter implication is for marks already on the register. Reclassifications such as the move of eyeglasses to Class 10 mean that older registrations and pending applications may no longer align neatly with the current edition, and renewals or extensions filed without attention to the change can introduce gaps.

This is routine portfolio hygiene rather than a crisis, but it rewards the disciplined. Businesses with broad product ranges, and the advisers who manage them, gain from auditing existing filings against the 13th edition before the next renewal cycle, confirming that each mark still covers what the company actually sells.

Takeaway: a classification change is a standing invitation to check that your brand still protects your business.

So What

For founders, marketers and IP managers, the action is specific. Before filing or renewing in 2026, map every product and service against the 13th edition rather than last year’s wording, give AI and hosted-service offerings their proper place in Class 42, and audit existing registrations for goods that have shifted class. The update does not expand what a trademark can do, but it sharpens how accurately a mark describes a modern business, and accuracy is what turns a registration into real protection. The companies that treat reclassification as a deadline rather than a footnote will hold cleaner, more defensible brands.
