Products under patent would already be charging the monopoly price regardless of a shortage. That's what a patent is supposed to do -- cause prices for new drugs to be temporarily high to provide the incentive to develop new drugs. The limit for this is how much better the new thing is than the old thing, such that if you charge more than that people switch back to the old thing.
This obviously kind of sucks when the drug is the difference between life and death, but those are also the drugs we most want a large incentive to develop, and that's why the patents eventually expire.
> Consider the example of a Taylor Swift concert. Are scalpers creating more supply by raising the prices of tickets or is it pure rent seeking?
Scalpers are trading time for money. You want tickets that would otherwise sell out but you don't want to wait in line, so you pay someone to wait in line for you. It causes tickets to be available at the higher price instead of being sold out and unavailable at any price. The way to prevent the rent seeking is to auction off the tickets to begin with so the money goes to the artist instead of the scalpers.
