"What we just went though In Germany is the action brought to the Federal Patent Court...which looks like the end of the process...IMO"

...against the decision of the Federal Patent Court "Bundespatentgericht" can be appealled only before the highest German Court the "Bundesgerichtshof" within one month. If this period elapses the decision becomes legally binding. The costs of the proceedings are to be paid by the party who lost.

Of course it is possible to seek a new lawsuit before the "Bundespatentgericht" by a third party with new material which didn't show up before but in this case costs and chances should be balanced thoroughly.

I hope I could help.
