Did you receive an irregularity letter from WIPO? Why the classification seems good for your Office of origin and not at WIPO? In this webinar, we will review common mistakes from Madrid System users and we will give you the tips to avoid them. You will be able to ask all your questions to our Madrid System specialist during the live Q&A session after the presentation. This interactive presentation is for all current and prospective users of the Madrid System. This webinar will be held in English and presented by Aileen Umali and Anna Wakefield.
