Company patents
MannKind Corporation
MannKind Corporation's patent strategy reveals a strong, dual focus on "Pharmaceutical Preparations" (57.7% of portfolio) and "Drug Delivery Devices" (48.5% of portfolio), with a notable 77.8% YoY growth in "Drug Delivery Devices" in 2025, suggesting a renewed emphasis on the integration of drug formulation and its administration technology. While "Pharmaceutical Preparations" saw consistent growth through 2025, the significant decline in patenting activity across most categories so far in 2026, including an 86.4% drop in "Pharmaceutical Preparations" and a 62.5% drop in "Drug Delivery Devices," indicates a potential shift or slowdown in new patent filings this year, though 2026 data is partial.

Delivery systems specifically engineered to administer advanced drug formulations (e.g., microparticles, biologics, extended-release systems) to achieve precise targeting, controlled release kinetics, or enhanced therapeutic efficacy within the body.
Mechanical or electromechanical systems designed for precise, often self-administered, delivery of medicaments, including features for dose setting, needle insertion/retraction, and safety mechanisms to prevent premature activation.
Devices or systems designed to precisely measure and deliver specific doses of medication, often incorporating automated mechanisms, dose-limiting features, or hands-free operation.
Devices and adapters that enable the sterile and secure transfer of liquids, such as medications or diluents, between containers (vials, syringes, IV bags) while minimizing exposure to contaminants or air.
Processes and methodologies for the efficient and scalable preparation of complex heterocyclic compounds and their precursors, including specific reaction conditions, purification techniques, and intermediate compounds.
Systems that integrate digital technology, sensors, or connectivity to monitor, track, or automate aspects of medication administration, often providing data feedback, personalized recommendations, or secure logging.
Devices that assist in the physical modification or mixing of medications prior to administration, such as crushing solid drugs, cutting pills, reconstituting lyophilized products, or extracting from other devices.
Systems and devices for delivering gases, aerosols, or pressure support to the respiratory system, often including interfaces like masks and sophisticated control mechanisms for therapeutic effect or airway management.
Digital platforms and systems that deliver tailored therapeutic interventions, guidance, or recommendations to patients based on their individual health data, biometric feedback, and computational models (e.g., AI/ML, physiological simulations).
