Third paragraph should've read:

In my example, the car maker has annual revenues of $5B but only $50M of that is attributable to the MMP infringing tech. So if TPL/PTSC gets $1 in licensing fees for every $2000 in gross revenues the company makes (that equals a royalty rate of .05%), it would get a license fee of $2.5M. However, if you compare that $2.5M but if you compare that as a percentage of the gross revenues attributable to the MMP infringing tech, that's $2.5M/$50M, which is a royalty rate of 5%.
