- Freedom to operate confirmed
- Successful opposition against Regeneron’s patent EP 1 360 287 B1 for transgenic mice producing therapeutic human antibodies
Merus B.V., a biopharmaceutical company focusing on innovative human antibody therapeutics, announced today that it has successfully retained full freedom to operate for its proprietary transgenic MeMo® mouse. In opposition proceedings at the European Patent Office, the opposition division ruled on September 17 that European patent EP 1 360 287 B1, owned by Regeneron Pharmaceuticals Inc., was revoked in its entirety.
In 2012, Regeneron was granted a European patent entitled “Methods of Modifying Eukaryotic Cells”. The patent is part of Regeneron’s IP portfolio around its VelocImmune® mouse for therapeutic human antibodies. Merus filed an opposition against this patent in June 2013, thereby requesting revocation of the patent.
