What the data says.reading this examiner

Examiner Bin Qing Zheng maintains a pooled record across 1 art unit in Technology Center 2400. The examiner's allowance rate, across dozens of decided applications, is 68%. This figure represents the share of applications in the decided category (allowed and abandoned) and does not include pending applications. The allowance rate is computed from the examiner's complete pooled record and reflects historical disposition patterns across the art unit(s) covered.

How to read these numbers.

This pooled record aggregates all decided applications across the examiner's art unit(s). The allowance rate of 68% describes the examiner's past record and is not a prediction about any specific application. Pooled figures smooth variations across different art units and represent overall historical performance. Individual applications may vary based on claim scope, prior art, and prosecution history.

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 Bin Qing Zheng 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: 60 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.
