I agree with what you have written. However, the infringers abilty to request re-exam..after re-exam, after re-exam, etc. is stacked in their favor. We expend precious resources (both in money and distraction) in the process (agreed better than litigation). This is the part that makes my blood boil. I want to see a cap in this regard or the USPTO to say that enough is enough. While the patents may be stronger for the attacks in general, the soldier (company and shareholders) gets beat up in the process.
