Roche, Genentech, Chugai and Biogen have settled their dispute in the US District Court for the District of Massachusetts regarding Genentech’s Actemra® (tocilizumab) patents. Roche, Genentech and Chugai instigated proceedings on 23 July 2023, alleging that Biogen’s product, manufactured in China by Bio-Thera, infringed 20 US patents including US patent No 7521052 (method of treating rheumatoid arthritis) and US patent No 8398980 (IL-6R antibody subtype).
Biogen received FDA approval for Tofidence®, its biosimilar to Roche’s Actemra®/ RoActemra® on 30 September 2023, the only approved biosimilar tocilizumab in the US.
