Biocon Biologics Files IPR Against Regeneron’s Eylea® (aflibercept) Patent

Nov 20, 2023

Biocon Biologics filed an Inter Partes Review (IPR) petition against  certain claims of Regeneron’s US patent no. 10,888,601 relating to Eylea® (aflibercept).  The challenged claims relate to methods of treating diabetic macular edema and diabetic retinopathy.  Biocon Biologics’ petition asserts the same grounds as the earlier petition filed by Samsung Bioepis and instituted by the USPTO Patent Trial and Appeal Board (PTAB) in March 2023, and includes a motion for joinder with Samsung’s petition.
