You know what's funny? Manfred Trenz registered "Turrican" in January 2011, but in August "FACTOR 5 - Eggebrecht, Engel, Schmidt GbR" raised an objection. It's somewhat confusing as "FACTOR 5 - Eggebrecht, Engel, Schmidt GbR" also has an approved registration of the Turrican trademark. But then a third party appears, there's also an objection proceeding against Factor 5 by Fabio Serena who's got the Turikan trademark.
But well, this means that there still is a Factor 5. "FACTOR 5 - Eggebrecht, Engel, Schmidt GbR" was registered in May 2011. So they got all Factor 5 GmbH trademarks now.
