Similarity of goods and trade marks
Porsche has had a decision in its favour upheld by the CJEU which confirmed that it was able to rely on its trade mark registrations in respect of automobiles to defeat an application to register the mark CARRERA in respect of Class 9 goods such as DVDs and electronic equipment.
Non-use and trade marks
Ikea have lost their trade mark for IKEA in Indonesia apparently because of non-use of the mark for 3 years. The successful challenge was made by an Indonesian rattan furniture company which had also registered the trade mark IKEA. In Europe, the non-use period before trade marks can become vulnerable is 5 years.
