On 2 February 2021, the intervener, Grupa Chorten sp. z o.o., filed with EUIPO an application for a declaration of invalidity of the EU trade mark that had been registered following an application filed on 18 July 2016 for the word sign duch puszczy. (curia.europa.eu)
In the second place, it noted that, since that mark was descriptive of those goods on its filing date, it could not fulfil its function as an indicator of origin and, therefore, had to be declared invalid (nula) in accordance with Article 7(1)(b) of that regulation.(curia.europa.eu)
