It's good to win, but I think nearly everyone expected it. Likewise, while the tribunal ruled that Amkor owes Tessera royalties on a minority of the patents at issue, the structure of Tessera's standard licensing agreement makes that meaningless; one patent costs the same as ten.
It's fortunate that we were warned that this wouldn't be as clean a resolution as the prior arbitration. Apparently, dollar figures will be settled by subsequent legal action. So no nice quick payment and end of legal expenses. Still, I'd like to be one of Tessera's lawyers: addd this to the trials related to The Wireless Matter (actually, this is largely about that too), and they have a full slate of lawsuits already decided in their favor with only the damage awards in question.
Most companies, especially including Tessera in the days before its new policy regarding legal developments, would have a statement with Q & A after a development of this importance. I can hope.
