On 25 July 2022, BioNTech SE and BioNTech Manufacturing GmbH (collectively, BioNTech) and Pfizer Inc. (Pfizer) (collectively, Plaintiffs) filed suit 1 in the District of Massachusetts against CureVac AG (CureVac or Defendant). Plaintiffs seek declaratory judgment of noninfringement of the patents-in-suit, U.S. Pat. Nos. 11,135,312 ("Pharmaceutical composition containing a stabilised mRNA optimised for translation in its coding regions"), 11,149,278 (Artificial nucleic acid molecules for improved protein expression), and 11,241,493 ("Coronavirus vaccine"). This suit comes as a response to a June 2022 complaint filed by CureVac against BioNTech SE and two of its subsidiaries in the German Regional Court in Düsseldorf, alleging infringement of mRNA-related intellectual property rights and seeking just compensation for the same. BioNTech SE and BioNTech Manufacturing GmbH are German companies with their principal places of business in Germany.
