A subsidiary of Swiss drugmaker Roche, Genentech, accused a Novartis unit, Sandoz, of infringing one of its patents, according to a complaint filed in a New Jersey court Monday.
The patent covers the drug Esbriet, which is used as a treatment for certain types of lung disease.
Genentech said in the complaint that Sandoz's breach of the patent was "knowing, reckless, and willful" and had resulted in "significant damage " to its company.
Roche has previously attempted to sue Sandoz over the same drug, but the lawsuit was thrown out in March 2022 after a U.S. judge found that parts of the Genentech patents were invalid.
Shares in both Roche and Novartis were down 1.4% in the first hour of trading.
