Abbott Laboratories v Corbridge Group Pty Ltd (No 2) [2001] FCA 810

Abbott Laboratories v Corbridge Group Pty Ltd (No 2) [2001] FCA 810

Claims 1 and 3 of the patent at issue are valid as they are sufficiently described, fairly based, and neither anticipated nor obvious in light of Australian common general knowledge or prior art. Claim 4 (and claims dependent on it) are invalid for lack of fair basis and lack of essential features. A statement in distributed user literature stating the ExacTech Blood Glucose Sensor could only be used with certain strips was misleading and deceptive, contravening section 52 of the Trade Practices Act.
