Reply to comment by the_fungible_man in The Vyvanse patent expires this year. How long does it usually take generic alternatives to get approved, and how much of a reduction in cost is expected on average? by paleselan1

The main patent expired Feb 24. But they are granted 6 months beyond that for exclusivity still for pediatric patients and supposed to use this time to study effects on kids. Basically most drug companies get a 6 month extension for pediatrics as they delay generics getting a chance and get extra time to rake in full price money and pretend to be studying effects on kids even if they’ve already had a decade to do so. So we have to wait til after Aug 24 2023.

They can't extend the life of the patent. They can claim that the process for making the drug is patented, and they can claim multiple steps in the process to make the drug are patented. Generic companies would have to see if they can make the drug without violating these patents, or they might have to challenge them.
