PCT application: Entry into the German national phase – deadline, requirements and official fees
An international patent application under the Patent Cooperation Treaty (PCT) gives applicants the advantage of initially covering more than 150 contracting states with a single filing. However, this does not yet create patent protection in Germany. By the end of the international phase at the latest, the application must be moved into the national phase before the German Patent and Trade Mark Office (DPMA) or into the European regional phase before the European Patent Office (EPO). Applicants opting for the direct route via the DPMA should pay particular attention to the 31-month deadline as well as the required formalities and official fees.
