A NOTICE OF DESIGNATION OF RELATED CIVIL CASES was filed with the court. It indicates that two similar cases are pending in the same DC District Court which arise from the same facts and share common issues of law:
Hesai Technology Co., Ltd. and Hesai Inc. v. U.S. Department of Defense et al., No.1:24-cv-01381;
Advanced Micro-Fabrication Equipment Inc. China et al. v. U.S. Department of Defense et al., No. 1:24-cv-02357
So, its not just DJI suing the DOD. There are at apparently least two other entities who object to their DOD listing as military companies.
