Dr. Bernd Hauschel, head of technology at Blankophor said, “Even though we have a different view on the decision of the European Patent Office, we do respect their decision after we lost the opposition case against Archroma’s patent.”
“For this reason, we decided to enter into a license agreement to avoid any infringement of the Archroma patent in the context regarding our products, as we also like our patents to be respected,” he added. (AR)
