// READING THIS EXAMINER

What the data says.

David E Choi maintains a public record spanning 3 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across hundreds of decided applications pooled from these art units, the allowance rate stands at 80%. The allowance rate ranges from 74% to 96% across these art units, reflecting variation in the mix of applications and outcomes within the examiner's portfolio. This pooled figure represents applications that were either allowed or abandoned; pending applications are excluded from the calculation.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates outcomes across multiple art units in TC 2100, presenting a single pooled allowance rate rather than unit-by-unit breakdowns. The 80% figure describes the examiner's historical record of decided applications and is not a prediction of any specific application's outcome. Pooled data masks variation among individual art units; the range (74% to 96%) indicates that allowance rates differ across the examiner's assigned art units, depending on the subject matter and application characteristics within each unit.

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 →

// BY ART UNIT

The record, art unit by art unit.

Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner David E Choi 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 July 14, 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: 816 applications.

Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes. 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.
