Janssen’s redacted public brief in support of preliminary injunction regarding Amgen’s Stelara® (ustekinemab) biosimilar

Janssen Biotech, Inc. has filed a redacted, public version of its opening brief in support of its motion for a preliminary injunction in proceedings relating to Amgen’s Stelara® (ustekinemab) biosimilar.  Janssen is seeking to enjoin Amgen, Inc. from manufacturing and using in commercial quantities, offering to sell, selling within the United States, or importing for commercial purposes into the United States its ABP 654 biosimilar product.  We previously reported that Janssen initially asserted two patents: US Patent Nos 6,902,734 (API) and 10,961,307 (methods of treating ulcerative colitis).  In its redacted brief Janssen states that while it has also asserted four ‘manufacturing’ patents, it is seeking a preliminary injunction for the duration of the proceedings based on only two of these: US Patent Nos 9217168 and 9475858.  We also previously reported that Janssen refiled its preliminary injunction motion after its original motion was denied because it did not comply with the court’s page limit requirements.
