// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates examination data across the examiner's art unit(s) in TC 2100. The 60% allowance rate describes past outcomes across 337 decided applications and is not a prediction of any specific application's outcome. Pooled figures smooth variance across art units and reflect overall historical performance. Each new application presents its own claim set, prior art, and examination circumstances. Aggregate statistics are correlational summaries only and do not establish causation or predict individual results.

These are aggregate statistics from this examiner's past public record — not predictions about any specific application. The per-art-unit figures below show how the record varies across art units. Our approach to patent prosecution →

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Herng Der Day has a public record within Technology Center 2100. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated June 25, 2026. The overall allowance rate is total allowed divided by total decided applications (allowed plus abandoned) across all art units — not an average of the per-art-unit rates; pending applications are excluded. Figures are rounded for display. Pooled sample: 337 applications.

Where this page compares an examiner's allowance rate to an art-unit average, that comparison is a factual description of the public record, not a characterization of any individual examiner's conduct or competence.
