The Federal Court of Appeal (FCA) held that it is abuse of process for a generic or biosimilar manufacturer to split its case across multiple notices of allegation (NOAs) under the Patented Medicines (Notice of Compliance) Regulations (Regulations). Reversing the Federal Court (FC), the FCA found that the generic or biosimilar manufacturer should raise all of its allegations in its NOA, and it should not keep some in reserve in the event that it is not initially successful.
