Article 105
Where a person registers for himself a mark belonging to another, knowing that the latter had been using the said mark, the user of the mark may request the competent court to invalidate it, provided that the proprietor of the mark had made continuous use of the mark for at least one year before the date of the infringer's application for registration.
Note — Where a person had been using a mark for at least one year before the mark was registered, its registration by other persons shall not prevent the continued use of the mark by the prior user.
