Microdosing System for Medical Use

Assignee: Hoffmann-La Roche Inc. (a Roche affiliate)
Patent Number: 12,357,748 B2
Filing Date: October 18, 2019
Patent Issued: July 15, 2025

What It Covers

This patent protects a medical dosing system tailored for micro-dispensing very small, precise volumes of therapeutic fluids — specifically designed to deliver aseptic fluids in tiny dosage increments (less than 100 µL) accurately and reproducibly. The system includes:

  • Microdosing pump architecture: A peristaltic or similar pump configured such that it can transfer very small fluid volumes into a container with high precision (±3 µL).
  • Use cases: While the patent’s mechanics can apply across multiple therapeutic areas, it’s especially relevant to injectable drugs and biologics where precise small-volume delivery can improve dosing accuracy, safety, and patient outcomes.
  • Medical applications: Potentially supports devices that deliver vaccines, hormones, insulin, or other potent biologic agents in tight therapeutic ranges.

Why It’s Important

1. Diagnostics and Therapeutics Integration

Roche is a leader in in vitro diagnostics and therapeutic delivery systems. A patent covering microdosing delivery technologies aligns with critical trends in personalized dosing and precision medicine, particularly relevant for sensitive analytes and biologics where tiny dose shifts matter.

2. Enhances Chronic Disease Management

Devices that precisely deliver small dosages are particularly valuable in diabetes care (Roche’s core area) and other chronic conditions requiring regular dosing. Improved dosing systems can reduce side effects and optimize therapeutic effects — a commercial advantage.

3. Broad Platform Potential

Though filed years earlier reinforces Roche’s platform IP in delivery technologies that can be licensed or underpin future medical device products beyond diagnostics — including automated injectors, continuous infusion systems, or microfluidic dosing devices.

4. Competitive Positioning

Owning core patents in delivery apparatus technology strengthens Roche’s position against med-tech competitors in an increasingly crowded and regulated device market.

Summary

U.S. Patent No. 12,357,748 B2, issued in July 2025 to Hoffmann-La Roche Inc., covers a microdosing delivery system for precise medical fluid administration — a foundational technology for devices in diagnostics and therapeutics. Its importance lies in improving dosing precision for sensitive medical treatments and in fortifying Roche’s intellectual property footprint in the medical device and drug delivery arena at a time when personalized medicine and accurate therapeutic dosing are increasingly critical.
