The EPO granted European patent EP4262672A1 to Koska Family Limited for piercing connector technology used with pre-filled plastic vials. The patent application, filed by inventors Marc Koska and Jeff Price, covers IPC classifications A61J 1/06, A61J 1/20, A61J 1/14, A61M 5/19, A61M 5/28, and A61M 5/32, representing a comprehensive scope of vial-to-syringe and vial-to-infusion-set connection systems. The patent is designated for protection in all 31 European Contracting States including DE, FR, GB, IT, ES, NL, and other major markets.

Medical device manufacturers and pharmaceutical companies utilizing pre-filled vial systems in the European market should evaluate whether their products incorporate similar piercing connector technology.
