Let me say first of all, I am no patent expert....but those two items I highlighted..esp. the last one, seems to me that the german system for patent approval has looked at the obviousness side of the issue and we still passed their "court"... JMO...as the last item states...

The examiner should always bear in mind that the invention is already part of his/her knowledge when he assesses whether or not the invention was obvious at the date of filing or the date of priority. A retrospective approach would not be appropriate.
