Reply to comment by ozwegoe 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

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.
