The appointment of judges for the UPC seems to be well on its way. In fact after approving a list of candidates in July during its 6th meeting, the Preparatory Committee is now in the process of notifying the applicants of their eligibility for becoming a UPC judge and whether or not they would require further patent litigation training.
It is however only a press-selection and candidates will have to submit a formal application if they actually wish to become a judge at the UPC. The formal application process has not yet been made public.
