AbbVie Inc. v. MedImmune Limited

The 1995 agreement, arising from a research collaboration that resulted in the antibody adalimumab, the active ingredient in the drug Humira, is governed by British law. The agreement licensed AbbVie to practice the 516 patent but AbbVie does not presently practice it. The agreement required AbbVie to pay royalties on certain sales “until the last to expire of [certain] Patents or the expiry of fifteen years from the date of First Commercial Sale of a Product by [AbbVie’s predecessor] . . . (whichever is later).” The last of those patents to expire is the 516 patent, with an expiration date in June 2018. The first commercial sale occurred in January 2003. AbbVie’s obligation to pay royalties either ceased in January 2018 (based on the first commercial sale) or will cease in June 2018 (based on the patent’s expiration date). AbbVie sought a declaratory judgment that the patent is invalid, arguing that a declaration of invalidity would constitute expiration under the contract, but did not seek the contract’s interpretation. The Federal Circuit affirmed dismissal the complaint. AbbVie does not practice the patent and is not at risk of an infringement suit. Even if AbbVie had standing, interpretation of the agreement would implicate the rights of the British government, which jointly owns the patent through one of its research councils. Deciding the invalidity question would not resolve the parties’ ultimate dispute and would raise concerns about foreign law and sovereign immunity. View "AbbVie Inc. v.
