Lucian Enescu In Romania, the holder of a previously registered trade mark (or application), or of a notorious trade mark may, under law no 84/1998, file an opposition to the registration of a new trade mark (within three months from the date when it was published in the Official Gazette). The opponent may consider the new sign as being prejudicial to their previous right if it is identical or similar to their own trade mark or if it protects identical or similar products as the ones protected by their own trade mark. An assessment in the case of identical marks is simpler. For similar trade marks, three possible types of similarity must be considered when analyzing a new trade mark for registration: visual, phonetic and semantic.
