|Nightmares, perhaps -- but no bad faith|
The Intellectual Property Court didn't need to rule on that issue, since the company failed on the facts: it had not established the fame of its own mark or the bad faith of the defendant, both of which were requirements under Article 6bis. There was evidence enough that Iron Maiden was a well-known rock band, but this did not mean that its reputation extended to goods in Class 25. Accordingly it could not be presumed that the defendant registered the mark IRON MAIDEN in bad faith.
