On 24 July Bulgaria ratified the Protocol on Provisional Application of the UPC Agreement (Protocol). Four more ratifications/declarations are needed, including Germany, for the Protocol to come into effect and allow the practical workings of the Unified Patent Court (UPC) to be established in preparation for the court coming into operation, which will happen once the UPC Agreement (UPCA) itself has been sufficiently ratified. In both cases, ratification by Germany is a prerequisite. Recently reported comments from the Chairman of the UPC Preparatory Committee have revealed that there may be at least a 6-8 month delay once Germany is ready to ratify the UPCA, given how much needs to be done for the UPC to be ready to open its doors. It therefore looks increasingly unlikely that the UPC will take effect before Brexit unless Germany ratifies the Protocol in the next few months.
