No, a brand that you have already registered does not automatically change when the class layout is updated. The protection you received when you registered remains as established, even if the glossary used to fill classes is added or rearranged later. What matters is when you apply for a new application and when you're thinking about expanding your existing brand.
The class classification used by BOIP and EUIPO is based on the NICE classification: an international list of 45 classes of goods and services managed by the World Intellectual Property Organization. This list is updated periodically: terms are clarified, new products and services are included, and sometimes a description shifts from one class to another. For those who want to apply for a trademark, that means one thing above all: use the current, harmonized terms from TMClass, not an older version that you copied somewhere.
What the update does and doesn't touch
An updated classification does not work back. A trademark that is registered under a description that was correct and current at the time of application remains valid as registered. The registers do not update existing entries ex officio because the terminology has been updated elsewhere. What changes is the list with which new applications are reviewed, and how a registry employee reviews an unclear term.
That is also why the word is automatically misleading here. There is no process to reclassify your existing brand. If you do nothing, the rights you already have will not change. If you are unsure whether your current description still matches what your company does today, give the free brand check in a few questions a first indication of that.
What it's about: the request itself
When preparing an application, the class format is the part that causes the most discussion, which is exactly where an updated classification comes into play. A description that was still common two years ago may now be considered too vague, or, on the contrary, outdated because a more precise term has become available. Registries review the description you submit against the current list, not against an earlier version.
For existing trademark owners, this is particularly relevant when they want to extend their protection, for example because the company has started offering a new service. Then we look at the current format, not that of the original request. On the page where we find out which request suits you for each situation you can read how this consideration is made in practice.
And in case of extension?
Renewing a brand is not a new class classification assessment. You renew enrollment as registered, for the same classes and the same description. An updated NICE classification is therefore no reason to change anything upon renewal, nor do the registries ask for it. What trademark owners do run into is that, over the years, an old description does not cover what the company does now. However, that is a different consideration than a classification change, namely whether the existing protection is still in line with today's practice, and that consideration is independent of the extension moment itself.
Where the information comes from
The Nice Classification itself, with the most current class structure and the harmonised terms from TMclass, is publicly available for consultation. We use the same sources to prepare applications: the official classification and the registers of BOIP and EUIPO themselves. To learn exactly how we do that and which steps are involved, please read the page where we explain where our information comes from.
For a specific question about the class structure of your own mark, this article provides a general framework, not advice for your situation. If you are uncertain whether your current description still aligns with what your business does, a professional representative or lawyer is the appropriate party to assess that; we prepare applications and provide alerts, but we do not give legal advice.
In brief
An updated Nice Classification does not affect existing mark registrations and has no effect on a renewal. However, it is relevant for a new application and for an extension to additional classes, because the application will then be assessed against the terms in force at that time.
