// READING THIS EXAMINER

What the data says.

Jae Un Yu maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning three art units. Across more than a thousand decided applications, the examiner's allowance rate stands at 91%, calculated as the share of applications that were either allowed or abandoned relative to all decided applications in the pooled record. The allowance rate across the examiner's art units ranges from 80% to 98%, reflecting variation in the decided record within individual art units. This record represents the aggregate of the examiner's work across multiple subject areas within TC 2100.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's decided applications across multiple art units into a single statistic. The overall allowance rate reflects past decisions and describes what has occurred in the examiner's record to date. It is not a prediction of the outcome of any specific application. Individual art units within the same technology center may have different allowance rates. Pooled figures mask this variation; they serve as a summary of the examiner's aggregate history and are historical in nature only.

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

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Jae Un Yu 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: 1,122 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.
