Whichever date falls later is when other manufacturers may apply to sell copies. Price typically falls steeply within a year of that point, and with it any company's ability to recover the cost of new research on the molecule. That is when it becomes a candidate for the ledger on the first tab.

Who funds the trials matters after protection lapses. Company-funded work usually stops once exclusivity ends; university, hospital and government-funded work does not, and is the research most likely to continue on this molecule afterwards.
