SAP customers shouldn't worry about the financial hit. SAP can pay the damages without having to rein back R&D. The pain may also stimulate it to greater competition with Oracle, both commercially and technologically, which will be beneficial for IT buyers.
Was the award fair? Well, IANAL, so I can't answer that. But my question is, if the basis of the award was "if you take something from someone and you use it, you have to pay", as the juror said, does that mean SAP gets to keep the licenses for which the court is forcing it to pay?
