Company patents
Fenwal, Inc.
Fenwal Inc. demonstrates a primary focus on medical device innovation, with Drug Delivery Devices constituting a significant 68.2% of its portfolio. While there was a notable surge in patenting across several categories in 2024, including Healthcare Informatics (+72.7% YoY) and Separation Processes (Filtration, Distillation) (+83.3% YoY), the company appears to be shifting its priorities, as evidenced by the sharp decline in patenting across nearly all categories so far in 2026, with Pharmacy Containers / Devices, Laboratory Apparatus, and Business Methods & Fintech all showing a -100.0% YoY change.

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.
Systems and methods for non-invasive or minimally invasive collection and analysis of physiological data (e.g., blood pressure, electrolytes, genetic markers, B cell repertoire) to assess patient health status, screen for conditions, or aid in diagnosis.
Methods and compositions for identifying, quantifying, or characterizing specific biological molecules (e.g., nucleic acids, proteins, metabolites, antibodies) or microbial species, often for diagnostic, prognostic, or quality control applications.
Systems and components designed for precise, automated manipulation, transfer, and dispensing of liquid samples and reagents, often involving pipettes, robotic arms, and specialized sample containers.
Systems and methods for automated monitoring and dynamic adjustment of environmental parameters (e.g., pH, temperature, oxygen, nutrients) and fluid handling within bioreactors to optimize cell/tissue growth or product synthesis.
Hollow-fiber and flat-sheet membranes for blood purification, hemodialysis, hemofiltration, and related extracorporeal therapies.
Self-contained or modular devices designed to automate and integrate multiple steps of molecular diagnostic assays, from sample preparation to result interpretation, often for point-of-care or high-throughput applications.
Methods and apparatus specifically tailored for the expansion, differentiation, or genetic modification of cells for therapeutic applications (e.g., CAR T cells, progenitor cells) or for the production of specific biological products (e.g., cultured fat, RNA).
Miniaturized devices that manipulate small volumes of fluids (nanoliters to picoliters) through microchannels to perform laboratory functions like mixing, separation, reaction, and detection on a single chip.
Equipment and processes for separating solid particles from liquid or gas phases in industrial settings, encompassing mechanical screening, filtration of molten materials, and various filter media designs.
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.
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.
Development and use of engineered biological systems, such as organ-on-a-chip devices, dynamic hydrogels, or genetically modified cells, to mimic physiological conditions, study disease mechanisms, screen compounds, or develop cell-based therapies.
Systems and methods that use imaging technologies, computer vision, and augmented reality to provide real-time guidance, localization, and visualization during surgical procedures or for detailed anatomical assessment.
Membrane and depth filtration for industrial separation, gas purification, and bioprocess clarification including cross-flow, dead-end, tangential flow filtration, and oil/water separation.
Systems and methods for authenticating users, devices, or applications, authorizing their access to resources based on policies, and managing digital identities across various platforms.
