12 APR 2024 | US | Aflibercept Appeals Dismissed for Lack of Jurisdiction
As previously reported, on 27 December 2023, and in a judgment published on 31 January 2024, the US District Court for the Northern District of West Virginia held that Mylan and Biocon infringed eight claims of Regeneron’s US patent 11,084,865, in respect of formulations of aflibercept such as Eylea®. The Judge found asserted claims of two aflibercept method of treatment patents (11,253,572 and 10,880,601) to be invalid. Regeneron appealed and Mylan and Biocon filed cross-appeals.
On 12 April 2024, the Court of Appeals for the Federal Circuit dismissed the appeal and cross-appealson the basis that all parties agreed that the Appeals Court lacked jurisdiction pending a decision of all patents in dispute. This was agreed because only three patents out of the 24 asserted by Regeneron had been addressed in the 27 December 2023 decision and the infringement and validity of numerous patent claims are still pending in the proceeding.
A hearing of Regeneron’s motion for a permanent injunction following the Court’s decision that Mylan/Biocon infringe US 11,084,865 is scheduled for 2 May 2024, ahead of a status conference on 13 May 2024.

On 11 April 2024, the United States Judicial Panel on Multijurisdictional Litigation ruled that patent infringement actions brought by Regeneron regarding aflibercept biosimilars by Amgen, Mylan, Celltrion, Samsung Bioepis (2 actions) and Formycon involved “common questions of fact” and should be centralized in the Northern District of West Virginia.
Regeneron commenced five of its actions in the Northern District of West Virginia but commenced proceedings against Amgen in the Central District of California. The Amgen case will now be transferred and assigned to Judge Kleeh who is hearing the remainder of the actions.
There are 63 patents in issue across each of the six actions. In each case, Regeneron alleges infringement of a common set of 13 US patents covering its ophthalmic drug, Eylea® (aflibercept).
Of the common set of 13 patents, one (a formulation patent, US 11,084,865, expiring in June 2027) was held by Judge Kleeh to be valid and infringed in a decision issued in the first-filed Mylan action in December 2023. Seven of the patents are at issue in preliminary injunction proceedings due to be heard on 2 May 2024 in the Northern District of West Virgina actions against Celltrion, Samsung Bioepis and Formycon.
