The firm closely collaborates with 35 highly experienced technical counsellors in all scientific fields (eg, physics, chemistry, biochemistry, biology and electrical, electronic, chemical and mechanical engineering). They are all competent translators and also regularly provide consulting services of the highest quality, based on their technical expertise in all IP sectors.
