La décision de la Cour d’appel fédérale Apotex Inc. c. Sanofi-Synthelabo Canada Inc., 2006 FCA 421, (December 22, 2006) concerne un brevet de sélection “selection patent”. Selon Apotex, l’invention le juge de première instance a erré en traitant le brevet en cause (CA 1,336,777) comme un brevet de sélection valide.
Le juge d’appel a confirmé la décision du juge de première instance. Selon lui:
“[43] These findings of fact as to the difficulty involved in producing the claimed compounds and the impossibility of predicting the claimed advantages before the compounds could be produced and actually tested are amply supported by the record and unchallenged by Apotex (otherwise than by its attempt to recast these findings through its own : and in my respectful view flawed : vision of the person skilled in the art).”
