The UPC or Unified Patent Court is a single European Patent Court covering 24 countries. The competence of the divisions of the UPC’s Court of First Instance is governed by Article 33 of the UPC agreement, which provides quite detailed regulations.

For each type of action for which the Unified Patent Court has competence (action types A, B, C, D, E, F, G, H, I as defined in Art. 32 of the UPC agreement), the decision tree indicates before which division(s) that type of action can be brought, hereby considering several conditions as presented in Article 33 of the UPC agreement.
We found the decision tree quite insightful:
