What the data says.reading this examiner

Jeong S Park maintains an 82% allowance rate across hundreds of decided applications in Technology Center 2400. The examiner's record spans two art units (2417 and 2454). The allowance rate ranges from 77% to 100% across these art units, reflecting variation in the decision patterns within each assigned art unit. This pooled figure represents allowed and abandoned applications and excludes pending cases. The 82% rate is a factual summary of past decisions and does not forecast outcomes in any individual application.

How to read these numbers.

A pooled record aggregates all decided applications across an examiner's assigned art units. The overall allowance rate describes historical disposal patterns, not predictions for specific cases. Variation across individual art units (shown in the range) reflects differences in application complexity, subject matter nuance, or other factors within each art unit. Pooled figures are useful context for understanding an examiner's past record but are not predictive of any particular application's outcome.

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 Jeong S Park has a public record within Technology Center 2400. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 22, 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: 878 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.
