A proposed TM must fulfil certain conditions in order to be accepted for registration by the Greek Trademark Office. We mention below the most important reasons that can prevent the final registration of a TM application: The proposed TM is identical or similar to a pre-filed TM that covers identical or similar goods or services or even different ones, provided though, that the pre-filed TM is a mark of fame. However, the rejection of the application for such reason (relative ground) depends on a successful decision on an opposition filed by any third party concerned. A search in the TMs that already exist is suggested before the filing of a new TM application in order to avoid unnecessary expenses. It is not sufficiently distinctive, so that consumers can not identify it with the products/ services that come from a particular company, or distinguish it from other TMs identified with similar products/ services of a different company. It consists exclusively of signs or elements that declare the kind, quality, quantity, intended purpose, value, place of origin or time of production of the goods or of rendering of the service, or other characteristics of the goods or service. It consists exclusively of signs or indications which have become customary in the current language or in the bona fide and established practices of the trade. It violates public order or morality. It is misleading or deceiving for customers especially regarding the nature, quality or place of origin of the goods or service. It includes badges, emblems or escutcheons which are of particular public interest, unless the consent of the competent authority to its registration has been given. It is filed in bad faith.
