Do you have any data on the quality of the patents? I thought the Motorola ones were mostly standards-essential and were a "second tranche" after the cream of the crop was previously sold off. But I can't find a good reference that I believe...
It's anyone's guess. How do we know how many patent suits were avoided because Google had a new arsenal to fight back with? How many new patents have Moto engineers filed since the purchase? How do we put a dollar value on the hardware expertise that Google picked up in the purchase?
