AstraZeneca Reaches Agreements With Teva Pharmaceuticals Regarding Nexium And Prilosec US Patent Litigations


AstraZeneca announced today that it has entered into an agreement with Teva Pharmaceutical Industries Ltd. and affiliates (collectively “Teva”) to settle patent litigation regarding Teva’s proposed generic version of AstraZeneca’s Nexium delayed-release capsules (esomeprazole magnesium).

As part of the Nexium settlement agreement, AstraZeneca has granted Teva a license to enter the US market with its generic esomeprazole on 27 May 2014, subject to regulatory approval, or earlier in certain circumstances. Teva has conceded that all patents-at-issue in Teva’s US Nexium patent litigations are valid and enforceable. Teva has also conceded that six Nexium patents would be infringed by the manufacture or sale of Teva’s US generic esomeprazole. The US District Court for the District of New Jersey will enter a Consent Judgment and corresponding Nexium patent litigations will be dismissed.

In a separate agreement, AstraZeneca and Teva have agreed to settle patent litigation related to Prilosec (omeprazole). Under this agreement, Teva will make a one-time payment to AstraZeneca for past infringing sales. The terms of this agreement are not financially material to AstraZeneca. AstraZeneca and Teva will jointly file a Stipulation of Dismissal with the US District Court for the Southern District of New York.

Merck Sharp & Dohme Corp. (formerly Merck & Co., Inc.) (“Merck”), through KBI Inc. and KBI-E, and under the terms of Merck’s restructured partnership with AstraZeneca, announced in 1998, also entered into the settlement agreements.
