What the data says.reading this examiner

Jun Fei Zhong maintains a public record spanning one art unit within Technology Center 2400. Across hundreds of decided applications, the examiner's allowance rate is 36%, representing the percentage of applications in this pooled record that were allowed rather than abandoned. This allowance rate reflects the examiner's historical disposition on applications that have reached a final decision. The record aggregates all completed applications within the examiner's jurisdiction and does not distinguish among different art units or application types.

How to read these numbers.

This pooled record combines applications across all art units in which the examiner operates. The aggregate allowance rate describes the examiner's past record on decided applications and reflects historical outcomes only. Aggregate figures do not constitute predictions about any specific application. Individual art units may show different rates; those details appear separately. Pooled statistics provide context for the examiner's overall record but do not indicate how any particular case will be examined or resolved.

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 Jun Fei Zhong 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: 241 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.
