Ten years ago the Austrian Supreme Court decided a case concerning Mazda and a tuning company. The tuning company had offered its chip tuning parts for a range of cars. It also named on its website the car types for which it offered these chips. For that it used the cars’ word marks and the figurative marks (logos).

    Austria: Examining the law around bad faith trade marks
    Until 2017, it was clear from several decisions of the Austrian Supreme Court that trade marks registered in bad faith were invalid and therefore could be successfully attacked any time and that asserted rights based on them would be rejected as immoral. However, the decisions went further: the mere use of that sign was held to be inadmissible and therefore could be forbidden as such without any other reason.
