That&#x27;s not a very useful way to look at it. (1) If Ericsson overall costs were just 4% bigger, you would be saying: &quot;10000% of Ericsson profits came from Apple&quot;, (2) R&amp;D that led to those patents likely had staggering costs, which may or may not have been fully amortized. It&#x27;s not just the engineer salaries of those who filed the patents either, likely the whole company structure, buildings and all, were instrumental in getting those technologies developed. So while the cashflow is mostly free, it is not pure profit.
