The European Patent Office (EPO) is a large European institution with offices in The Hague and Munich. EPO asked Prospex to develop a training trajectory to enhance the collaboration and negotiation capacities for their senior staff. EPO’s activities are very complex, situated within a delicate framework of internal and external stakeholders thus potential conflicts are a part of daily life. Prospex prepared training in close collaboration with the HR department. The tailor made trajectory was offered to selected staff with maximum involvement of the participants and role-plays on real life cases.
