Coopers Animal Health Australia Ltd v. Western Stock Distributors Pty Ltd & Ors [1986] FCA 359

The petty patent was invalid.

'Whether the invention claimed in the petty patent was obvious and did not involve an inventive step having regard to what was known or used in Australia on or before the priority date.'

By then the claimed invention was not novel because earlier patent publication and non-confidential Spurt field trials disclosed formulations falling within the petty patent claim. In any event, even as at 21 November 1980, the claimed invention was obvious:...
