The provided patent text indicates that "Family has litigation" and links to a "Global patent litigation dataset” by Darts-ip and "Unified Patents PTAB Data" and "Unified Patents Litigation Data", but these links are not directly searchable in this environment for further details such as specific plaintiffs, defendants, or filing dates for all the listed district court cases. The current status for the PTAB case IPR2025-01271 is "Pending - Instituted". Without further access to these external databases, I cannot provide the missing details like plaintiffs, defendants, and specific filing dates for the district court cases, or an outcome for any of the cases.
