As explained in the OHIM web site, "The Pan-European Seal Professional Traineeship Programme (the Pan-European Seal) is a comprehensive IP programme which bridges academia and the IP labour market. It is promoted in partnership by two of the world's largest IP offices, the Office for Harmonization in the Internal Market (OHIM) and the European Patent Office (EPO) together with their strategic University partners.
The Pan-European Seal is an IP Programme that covers many academic areas. Through it, high-achieving young university graduates can access paid traineeships in OHIM and the EPO, helping them get a foot in the door of the competitive world of IP through valuable on-the-job multicultural professional work experience.
The Pan-European Seal will offer 100 traineeship posts every year, administered by both Offices (number of posts offered by each Office will be determined annually)".
