// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile presents pooled data across multiple art units, meaning the figures combine examination records from different art-unit classifications. The allowance rate of 72% describes the historical record across all decided applications and is not a prediction for any individual case. Aggregate statistics describe past outcomes and do not forecast the disposition of any specific application or indicate how a particular art unit will handle a given matter.

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 Hieu C Le 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: 29 applications.
