## Nice Classification Overview

The [Nice Classification](https://www.wipo.int/classifications/nice/en/) is an international system for classifying goods and services for trademark registration. It comprises **45 classes** — classes 1–34 cover goods and classes 35–45 cover services.

## Use Cases

<!-- TODO: describe intended use cases, e.g.: -->
- Training text classifiers to predict Nice class from product/service descriptions
- Building search and recommendation systems for trademark registration
- Semantic analysis of goods and services terminology
- Augmenting NLP pipelines with structured IP classification data

## Limitations

<!-- TODO: add any known limitations, e.g.: -->
- The dataset is a snapshot from a specific point in time and may not reflect the latest TMclass updates
- Only English-language terms are included
- Some `approval_type` values are empty, indicating unspecified status
