Vericore Ltd v Vetrepharm Ltd & Anor [2003] EWHC 111 (Ch) (06 February 2003)

Vericore Ltd v Vetrepharm Ltd & Anor [2003] EWHC 111 (Ch) (06 February 2003)

The claims are invalid for anticipation and/or obviousness because the prior art (D1, D2, D9) discloses or makes obvious the use of pyrethrum/pyrethrins (natural or synthetic) for treating sea lice in salmon, and the term 'pyrethroid' in the patent includes both natural and synthetic compounds. The skilled addressee would have both fish health and toxicology expertise, and the use of a suspension is not inventive.
