Cytec Industries Inc. v Nalco Company (No 4) [2024] FCA 1318

Cytec Industries Inc. v Nalco Company (No 4) [2024] FCA 1318

Nalco's amendment application was refused because the amended claims did not overcome deficiencies previously identified, namely lack of clear and complete disclosure and lack of support for the claimed invention, in breach of ss 40(2)(a) and 40(3) of the Patents Act 1990 (Cth); the amendments were not allowable under s 102(2), and, even if allowable, the discretion under s 105(1A) would not have been exercised in their favour due to futility and principles of finality.
