It sounds like you`re suggesting that, when dealing with each individual company, there would be a separate and descrete license executed for each patent/patent infringement and that, further, each such individual license would have a pre-established price tag and same price to any offender. Neither is correct.
Each company will have a license to use the tech cited in whatever patents are applicable, i.e., one license would cover X number of patents.
There is probably no set price tag, or even a specific proportion to sales type pricing structure for licenses or each patent being infringed. They will conduct a negotiation. While certainly there would be some basis of measurement for TPL to figure out how much money/terms to go after, and they would thereby come up with a price target, the other big factor is ``who are we dealing with, what is their history``. Also, there is the factor that TPL has pointed out - early licensees will get (supposedly) a better deal (allowing them, ultimately, to undercut their competition who will be paying more). So the price, regardless of other criteria, can be expected to increase as time passes and more licenses are executed.
So, one license per company (unless a new claim of infringement is brought based on infringement of a patent not covered in the original license), and price tag variable based on individual circumstance.
