Makes sense. Sorry for my miss the first time. :-)
So what this means is that the small players would give up before the big players even though the invention otherwise took the same amount of investments or has the same potential for reward back.
The shape of the exponential curve makes the time difference between small and big players giving up relatively small (if that difference exists in the first place.) Both have reasonably long time with reasonably low patent tax to develop the commercials before the tax starts really kicking in. The tax with my initial numbers breaks one million USD p.a in 10 years and 10 millions in 14 years.
