• The Federal Court of Australia has dismissed Sanofi's appeal against Amgen's PCSK9 antibody patents, ordering that Amgen's Repatha patent applications proceed to grant under Australia's pre-2013 patent laws.
• This Australian ruling contrasts with decisions in the US, where the Supreme Court invalidated similar Amgen patents for lack of enablement, highlighting significant jurisdictional differences in antibody patent protection.
• The case provides important precedent for other valuable antibody patents approaching the end of their term that are still subject to Australia's old Patent Act as biosimilars seek market entry.
