Anyone registering a trade mark often faces the same challenge: determining the appropriate classes of goods and services. The so-called Nice classification is the basis for this. It ensures that each trade mark is clearly categorised - an important step in defining the scope of protection and comparability.
However, manual searches in the PDF lists of the German Patent and Trade Mark Office (DPMA) are time-consuming and error-prone. This process can be significantly simplified with modern AI tools.
