Wake Forest University Health Sciences v Smith & Nephew Pty Ltd (No 2) [2011] FCA 1002

Wake Forest University Health Sciences v Smith & Nephew Pty Ltd (No 2) [2011] FCA 1002

Smith & Nephew did not infringe any claims of the patent, as KCI failed to prove S&N’s product possessed the essential 'screen means sufficiently rigid to prevent wound overgrowth' integer required by all claims in suit. This integer was also held to lack scientific meaning, rendering all claims in suit invalid for lack of clarity and sufficiency required by ss 40(2) and (3) of the Patents Act 1990 (Cth). Claim 49 was additionally invalid as a mere collocation. Novelty and inventive step grounds were not established independent of the key deficiency.
