Our cross-disciplinary team is composed of highly qualified Attorneys. Their profiles are issued of a variety of past professional experience (in companies, study offices, research laboratories, law firms, etc.) which – for the most part profiles – enrich themselves with their strong experience in higher education (engineering schools, ESSEC, ESC, doctoral schools, etc.) or in judicial expertise before the Court of Appeal.
Our Patent Team consists in engineers and PhD specialists whose competences run the whole gamut of most of the technical domains (mechanics and materials, biotechnology, immunology, electrical engineering, electronics, acoustics, physics, chemistry, etc). We can therefore assist you or your clients in practically all spheres of activity.
Our Patent and Trademark attorneys are registered with the European Intellectual Property Office and with the French Patent & Trademark Office: we are therefore able to represent you or your clients before these Offices.
Our IP professionals are also active members of the main national and international IP associations (INTA, PTMG, ACPI, CNCPI, APRAM, etc.) and regularly attend and speak in conferences dedicated to Intellectual Property.
