Amgen files motion to intervene in aflibercept proceedings

May 23, 2023

Amgen filed a motion to intervene in the proceedings on foot between Regeneron and Mylan in West Virginia relating to aflibercept, and has sought to unseal certain documents. Amgen argued that the sealing of the documents blocked the public’s right of access to Court documents, and that the Court has provided no justification for sealing a number of documents.

Regeneron sued Mylan in West Virginia in August 2022, alleging infringement of 24 patents relating to Eylea (including the ‘601 patent), and a 10 day trial has been set down for June 2023, which is 10 months after Regeneron filed its complaint.
