The main reason for the amendments is EU directive 2015/2436, to approximate the laws of the member states relating to trademarks, which has to be brought into force in Austria by the beginning of 2019. The main changes of the Trademark Act are that the period of protection of a trademark is 10 years from the date of filing, and the introduction of a new legal institution of a ‘guarantee mark’ certifying quality, accuracy, etc of goods and services.
