I did a short search in our national registry of trademarks, and for “Don Quixote” there are 3 results:
26.05.2006 - DON QUIXOTE GOURMET - Non existing anymore - MANCHACOMEX SL., MANCHACOMEX SL., Ballesteros de Calatrava, Ciudad Real, Spain - roles 29, 35 - Worded
04.08.2011 - DON QUIXOTE - Active - Aristocrat Technologies Australia Pty Ltd, Aristocrat Technologies Australia Pty Ltd, North Ryde, Australia - roles 9, 28, 41 - Worded
24.08.2018 - DON QUIXOTE DE LA MANCHA EXCELLENT - Active (conditions and disputed) - INTERPROFESIONAL DEL CONSEJO REGULADOR DE LA DENOMINACION DE ORIGEN "LA MANCHA" ICRDOLM, INTERPROFESIONAL DEL CONSEJO REGULADOR DE LA DENOMINACION DE ORIGEN "LA MANCHA" ICRDOLM, Alcazar de San Juan (Ciudad Real), Spain - roles 33, 35 - Image
So, first isn't existing anymore. The one from 2011 is active, last one from 2018 is disputed (most likely problem with the one from 2011), or problem with some part of name.
