"In fact, I don't know why they fool around with negotiations for years. It would save time and cost less to serve infringers with a lawsuit in Germany and the U.S. at the same time. A "shock and awe campaign" that, IMO, would lead to immediate negotiations, quick settlements and then drop the lawsuits at a minimum cost to us."

I agree. Also years of negoiations without results would provide proof of willful infringement. Which is much more serious a violation in Germany. Almost seems like a good plan that is coming togeather either by plan, or by accident, but should definately be acted upon.
