Regeneron adds further patents to Purple Book patent list

Apr 26, 2023

Regeneron listed additional aflibercept patents on the Purple Book patent list.  The Purple Book patent list records the patents exchanged between the originator and biosimilar applicant as part of the patent dance and suggests that another dance has begun with a second biosimilar applicant. There are now 46 aflibercept patents listed on the Purple Book, including the 24 asserted against Mylan in August 2022.
