ICOSA’s international presence is reflected in the animation of a network of foreign associates who work with national offices to protect and promote the inventions of ICOSA’s clients around the world.
ICOSA is also requested by patent offices abroad to become the patent attorneys of their clients at the French Intellectual Property Office (INPI), the European Patent Office (EPO) and the Belgian Office of Industrial Property (OPRI) on behalf of their clients.
