Trade mark consultants
The trade mark consultants list contains the names of all trade mark representatives who have requested to be included in the list provided by the IPI. In order to avoid any distortion of competition and in view of the lack of objective admission criteria, no selection is made. The IPI therefore cannot provide any information regarding the quality of the services offered by the listed representatives, nor guarantee the completeness of the list.
