CISCO has no chance of winning this case and it is obvious after reading court documents and they will be paying heavy price for it and it will affect their balance sheet and shareholder annual dividend as well. This could easily be multibillion dollars but they can restructure it in such a way that they don't have to pay all at once. It could be paid over the years just to save face. This is not even close they can't prove anything in court that is bottom line. Period.
So you are saying CISCO has no other options other than just finding typos on Chanbond's patent documents. From their petitions, they tried to invalidate Chanbond's patent but judges denied their claims, no proof that supported CISCO's claims. Let's see if they can prove "skillful artisan".
