BREAKING NEWS: Bayer Rivaroxaban patents survive first AU challenge by Sandoz with ~150 generic products approved

by | Nov 6, 2023

With over 150 rivaroxaban products approved (9 of them for Bayer), the outcome of the Sandoz challenge to the validity of the AU Bayer (Xarelto®) patents may be the case with the broadest commercial interest this decade.

Nine generic companies have multiple products approved (Accord (32); Alembic (28), Teva (24), Arrotex (23), Cipla (12), DRL (12), Torrent (12), Alphapharm (3), Sandoz (3)) and all of them will be disappointed by the impact of the first instance decision of Rofe J in Sandoz AG v Bayer Intellectual Property GmbH [2023] which was published last Friday.

The patents in suit are:

  • AU2006208613 (19 Jan 2026) entitled “Prevention and treatment of thromboembolic disorders”;
    • Finding: valid and infringed.
  • AU2004305226 (13 Nov 2024) entitled “Method for the production of a solid, orally applicable pharmaceutical composition”;
    • Finding: valid, but Bayer accepted this was not infringed based on the Court’s construction of the phrase “in hydrophilized form”.

Her Honour found the two Bayer patents in suit valid, and claims 3 and 4 of the ‘613 to be infringed (the 226 was not infringed by Sandoz).  The decision is appealable to the Full Federal Court prior to 1 December 2023.
