// READING THIS EXAMINER

What the data says.

Junchun Wu maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security), spanning one art unit. Across hundreds of decided applications, the examiner's allowance rate is 85%. This figure represents the share of decided applications—those allowed or abandoned—in the examiner's pooled record. The allowance rate is computed from applications that received a final disposition and does not include pending matters. This pooled record aggregates the examiner's work across all art units in TC 2100.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates data across all art units assigned to an examiner, presenting an overall view of historical dispositions. The allowance rate reflects past decisions on applications that reached final resolution. Aggregate figures describe what occurred in the examiner's record and are not predictions about any specific application. Individual art units may show different patterns; detailed per-unit data appears in separate sections of this profile.

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

The record, art unit by art unit.

Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Junchun Wu 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: 557 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.
