Company patents
NIPRO CORPORATION
NIPRO CORPORATION's patent strategy shows a strong, albeit recently declining, focus on Drug Delivery Devices, which constitute 40.5% of its portfolio but saw a significant -78.6% year-over-year drop in patent filings so far in 2026. Surprisingly, while many core medical device categories are seeing declines, the company appears to be shifting some attention towards Sterilization & Biocompatible Materials, which has seen a notable increase in filings so far in 2026 compared to 2025.

Engineering and material considerations for devices used in minimally invasive procedures, focusing on mechanical properties, deployment mechanisms, and interaction with biological tissues.
Minimally invasive medical devices, typically flexible tubes, inserted into body lumens to deliver substances, remove obstructions, or perform localized treatments like ablation, dialysis, or drainage.
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.
Hollow-fiber and flat-sheet membranes for blood purification, hemodialysis, hemofiltration, and related extracorporeal therapies.
Systems that provide therapeutic stimulation or field therapy through wearable devices, often incorporating physiological sensing and closed-loop feedback for personalized and adaptive treatment.
Implantable devices designed to repair, replace, or assist the function of blood vessels or heart structures, including stents, valves, and annuloplasty rings.
Design and application of devices that are inserted into the body or implanted to treat diseases, modulate physiological functions, or repair anatomical structures.
Use of alternating electric or magnetic fields at specific frequencies and intensities to achieve therapeutic effects, such as inhibiting cell proliferation (e.g., cancer) or modulating cytokine production.
Methods for producing glass-ceramic articles through controlled nucleation and crystallization processes, often involving specific thermal treatments to achieve desired microstructures and properties like strength or dimensional stability.
Materials and structures designed for implantation or tissue regeneration, focusing on properties like biodegradability, mechanical strength, cellular integration, and long-term in-vivo stability.
Glass articles treated with ion exchange or other chemical processes to induce a surface compressive stress layer, enhancing mechanical strength, scratch resistance, and impact toughness.
Application of coatings, layers, or chemical treatments to the surface of glass articles to impart specific functionalities such as UV blocking, anti-whitening, hydrophobicity, or adhesion for subsequent layers.
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.
Design and manufacturing of multi-pane glass units with an evacuated gap and specialized sealing technologies to provide superior thermal insulation for architectural or appliance applications.
Membrane-based separation for water purification, contaminant removal, desalination, and wastewater treatment, including reverse osmosis, ultrafiltration, and forward osmosis modules.
Multi-layer polymer films engineered to provide superior barrier properties against gases (e.g., oxygen), moisture, or aromas, often incorporating heat-sealing or resealing mechanisms for food and product preservation.
Structural elements within a container designed to secure, separate, cushion, or otherwise protect individual items or groups of contents from movement, shock, or damage.
Systems that employ imaging and image processing to automatically detect defects, verify states, or ensure quality control in manufactured goods, printed materials, or industrial processes.
Development of therapeutic approaches involving the genetic modification of cells (e.g., T cells, stem cells, macrophages) or the use of viral/non-viral vectors to deliver genetic material for disease treatment.
Methods and apparatus for disinfecting or sterilizing medical devices, waste, or environments, often employing radiation, chemical agents, or thermal processes, and including monitoring systems.
Focuses on the mechanical design, articulation, and actuation of hand-held or robotic surgical instruments, including improvements in stapling, cutting, grasping, and tissue manipulation.
Manufacturing and processing techniques for producing ultra-thin glass articles, often with enhanced flexibility and mechanical properties, suitable for use as substrates in electronic displays, foldable devices, or other advanced electronics.
Implantable devices used for the fixation, fusion, or replacement of bone structures, particularly in the spine and extremities.
Development of devices and methods for non-invasive or minimally invasive collection and analysis of physiological data, often from wearable sensors, to monitor health, activity, or specific conditions.
Devices or systems designed to precisely measure and deliver specific doses of medication, often incorporating automated mechanisms, dose-limiting features, or hands-free operation.
Technologies and systems for removing unwanted components or separating desired gases from a mixed gas stream, including adsorption, absorption, and membrane-based methods.
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.
