Trademarks are an important feature to distinguish a product or service from that of competitors and are often the most valuable assets of companies. New products can be successfully brought into the market only, if a secured trademark position is established in advance. Therefore, the success of companies very much depends on the conditions under which a trademark is filed and the protection thereof against infringers. It is therefore of utmost importance that companies have a trademark and brand strategy. This contains that the companies proceed to a trademark search in order to find out which trademarks are already existing in the market. Then, as a next step, the company has to decide which brands to use, taking into account that these brands should sufficiently differ to already existing prior trademarks. Furthermore, it should be taken into account that trademarks are the only intellectual property right that can be valid without a time limitation. Successful trademarks will remain an important task of each company for the whole time of its existence. The protection of Greek Trademarks can be obtained through filing before the Greek Authorities, European Trademarks are filed before the European Union Intellectual Property Office (EUIPO).
