Boehringer Ingelheim Animal Health USA Inc v Zoetis Services LLC (No 2) [2024] FCA 291

Boehringer Ingelheim Animal Health USA Inc v Zoetis Services LLC (No 2) [2024] FCA 291

All claims in the three patent applications were found invalid: primarily, because broad and dependent claims lacked inventive step by being obvious in light of common general knowledge and particular prior art. Certain claims also lacked sufficient disclosure, support, and failed to disclose the best method as required by the Patents Act 1990 (Cth). Consequently, the appeal was allowed, the cross-appeal was dismissed, and all opposed patent applications were refused. Costs were awarded in favour of the successful appellant, subject to a discount for costs incurred before a late amendment introducing the best method ground.
