(Reuters) - CureVac NV said on Friday it had filed an expanded patent infringement claim against Pfizer Inc (NYSE:PFE) and BioNTech over the use of mRNA technology and that a U.S. court had granted its request to transfer the trial.

The company said it filed a counterclaim alleging that Pfizer and its German partner BioNTech infringed on nine of its patents, broader than its original claim of three patents.

In July 2022, CureVac had filed a patent lawsuit against BioNTech over the use of mRNA technology in the companies' COVID-19 vaccine.

The transfer of the trial to the Eastern District of Virginia from the Federal District Court of Massachusetts is expected to accelerate progress of the case and allow for a likely 2024 trial date, CureVac said on Friday.

Pfizer and BioNTech did not immediately respond to requests for comment. 

Pfizer and BioNTech in response had filed a complaint with the U.S. District Court in Massachusetts, seeking a judgment that they did not infringe U.S. patents held by CureVac.
