OSI sued Teva in federal court in Delaware in March 2009, accusing the Israeli generic-drug maker of infringing patents 6,900,221, 7,087,613 and 5,747,498.
Tarceva is used to treat small-cell lung cancer. The litigation was triggered when Petah Tikva, Israel-based Teva applied to produce a generic form of the drug.
The order dismissing Teva as a defendant was filed March 15, according to court filings.
The case is OSA Pharmaceuticals v. Mylan Pharmaceuticals, 1:09-cv-00185-SLR, U.S. District Court, District of Delaware (Wilmington).
