The MDL court found that plaintiffs’ claims boiled down to failure to warn claims and, therefore, were preempted under the U.S. Supreme Court’s decision in Mensing.

Seven months before DexCom's continuous glucose monitoring device received FDA approval, Abbott sued DexCom, and the DexCom litigation team convinced the court that it lacked jurisdiction to hear the dispute when filed. The DexCom patent prosecution team filed requests for reexamination of each asserted patent, all of which were granted. The DexCom litigation team then persuaded the court to stay the case pending reexamination and later convinced the court to strike an amended complaint adding more patents.

Trial commenced in the MDL Court, the U.S. District Court for the Northern District of California, in 10 wrongful death cases, leading to settlements during trial of all but one of the remaining cases. After remand to the Central District of California and transfer back to the Northern District of California for trial, the remaining case settled.
