Professional Experience

Guillaume has mastered the aspects of his job as an IP Attorney, from drafting patent applications and their examination by the national patent offices to patent disputes to consultations on the validity and exploitation of patent rights. In particular, he regularly participates in Oral Procedures before the European Patent Office and handles legal actions.


Guillaume thus passionately tackles the IP issues facing many industrial companies, supporting their development strategies and providing them with practical expertise.


Broadly speaking, his technical field is mechanics, with particular experience in medical and surgical devices, industrial processes, health and wellness equipment (childcare, agri-food, body care, etc.) and temperature-controlled equipment. However, his initial training as a Centrale engineer allows him to understand a broad range of inventions.


He is also a member of the GRAPI (Groupe Rhône-Alpes pour la protection de la Propriété Intellectuelle [Rhône-Alpes Group for the Protection of Intellectual Property]).
