What This Patent Covers

This patent application describes a specialized tray and dry reagent station architecture for use in automated sample preparation instruments—critical components of clinical laboratory analyzers that process patient specimens (e.g., blood, serum, urine) in high volumes with precision and reliability.

Key aspects include:

  • Reagent Tray Design: A tray with multiple wells configured to securely hold tubes containing dry reagents, which are used in various diagnostic tests. The tray design ensures reagents are stably positioned during instrument operation.
  • Anti‑Rotation Mechanism: Each well includes an anti‑rotation feature to prevent tubes from turning during rotational movements of the instrument, improving reliability and reducing test errors.
  • Instrument Integration: The tray is designed to mount on a platform within the sample preparation instrument, enabling automated reagent access, robotic placement, and integration with fluidic and sensing systems that perform assay steps.

In essence, this invention enhances high‑throughput laboratory automation by improving how dry reagent cartridges or tubes are handled and stabilized during clinical sample processing.


Why This Patent Is Important

1) Core to Danaher’s Diagnostics Business
Beckman Coulter—now part of Danaher—derives a large portion of revenue from clinical analyzers and lab automation systems used in hospitals and diagnostic laboratories worldwide. Efficient reagent handling and sample prep automation are major selling points for these instruments. Any patented innovation that improves performance, throughput, or reliability can support market share and premium pricing.

2) Enables Better Throughput & Accuracy
Automated sample preparation instruments must reliably process large sample volumes daily. A tray that prevents reagent tube misalignment or rotation can reduce test failures, downtime, and manual intervention, driving efficiency—and thus demand—in clinical labs.

3) Strengthens Patent Portfolio in High‑Value Segment
Diagnostics and laboratory automation is a multi‑billion‑dollar global market. Patents protecting critical subsystems (like reagent handling) reinforce Danaher’s intellectual property moat and support long product lifecycles through differentiation and barriers to replication.

4) Cross‑Product Applicability
While the patent is specific to Beckman Coulter’s sample prep instruments, the underlying mechanical innovations could be adapted across different analyzers and robotic platforms, extending its commercial relevance beyond one product line.
