Mont-Saint-Guibert, Belgium - Celyad (Euronext Brussels and Paris, and NASDAQ: CYAD), a leader in the discovery and development of engineered cell-based therapies, today announced that the U.S. Patent and Trademark Office (USPTO) has decided to reject a new reexamination request of Celyad’s U.S. Patent No. 9,181,527, relating to allogeneic human primary T-cells that are engineered to be TCR-deficient and express a CAR. The patent remains valid and enforceable.

This is the fourth time that our US Patent for Production of Allogeneic TCR-Deficient CAR-T cells is challenged and each time, the USPTO has been favorable to Celyad. This patent is key for the players that are developing in the US allogeneic CAR-T cell approaches and it places Celyad in a very good position to optimize the significant potential of its allogeneic platform, either on our own or through strategic collaborations”, said Christian Homsy, CEO of Celyad.
