What the data says.

Etienne Pierre Leroux maintains a public record across two art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Of 1,591 disposed applications, 1,376 were allowed, yielding an allowance rate of 86%. The examiner's allowance rate ranges from 60% to 87% across these art units. This pooled record reflects decisions made in art units 2161 and 2171. The aggregate figure represents the historical outcome of decided applications and does not characterize performance in any individual art unit or predict results in future applications.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This examiner's record is pooled across multiple art units, meaning the 86% allowance rate is an aggregate statistic combining different technology areas within TC 2100. Pooled figures describe past decisions across all covered art units combined. The range (60% to 87%) indicates variation among individual art units but does not identify which specific art unit produced which rate. Aggregate statistics are historical snapshots and are not forecasts for any particular application.

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 Etienne Pierre Leroux 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: 1,628 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.
