Cubist Pharmaceuticals, Inc. (NASDAQ: CBST) today announced that it will oppose a motion filed by the Teva defendants to amend their answer to add a new defense in the patent litigation between Cubist and Teva pending in the US District Court for the District of Delaware. A motion for leave to amend the answer is a request to be permitted to add a new allegation. The Teva defendants seek leave to amend their answer to allege that US Patent Nos. 6,468,967 and 6,852,689 are unenforceable due to inequitable conduct.

Cubist filed a patent infringement lawsuit against Teva Parenteral Medicines, Inc. (TPM), Teva Pharmaceuticals USA, Inc. and Teva Pharmaceutical Industries Ltd.
