Persons who wish to be represented in proceedings before the National Institute of Industrial Property may only do so, for acts where the technical nature of the subject matter so requires, through the intermediary of industrial property attorneys whose specialisation, determined pursuant to the last paragraph of Article L. 422-1, is relevant to the act.
The provisions of the previous paragraph do not prevent the use of the services of a lawyer or those of a company or public establishment to which the applicant is contractually linked or those of a specialised professional organisation or those of a professional established on the territory of a Member State of the European Community or of a State party to the Agreement on the European Economic Area acting on an occasional basis and authorised to represent persons before the central industrial property service of that State.
