What the data says.reading this examiner

Wuji Chen maintains a public record in Technology Center 2400 across 2 art units. Over hundreds of decided applications, the examiner's allowance rate is 77%. This rate represents the share of applications in the decided population—those allowed or abandoned—and does not include pending applications. The allowance rate ranges from 76% to 78% across the examiner's art units with substantial records. The pooled figure reflects the examiner's aggregate output across these units and describes the historical record without indicating the outcome of any particular application.

How to read these numbers.

A pooled, cross-art-unit record aggregates data from multiple art units into a single overall allowance rate. This aggregate describes what occurred across the examiner's decided applications in the past and is a historical snapshot only. The range among individual art units shows variation within the examiner's practice. Pooled figures are not predictions for any specific application and do not account for differences in claim scope, specification, or prosecution history across individual cases.

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 Wuji Chen 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: 349 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.

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.
