What the data says.reading this examiner

Examiner Annan Q Shang maintains a public record in Technology Center 2400 spanning one art unit. Across hundreds of decided applications, the examiner's allowance rate is 71%. This figure represents the share of applications in the examiner's pooled record that were allowed, computed from the total of allowed and abandoned applications. The allowance rate reflects historical outcomes on decided cases and does not constitute a prediction for any specific pending application.

How to read these numbers.

This pooled record aggregates all of the examiner's decided applications across one art unit in TC 2400. The allowance rate of 71% describes what occurred in the examiner's past decided cases—allowed and abandoned applications combined. Pooled figures do not vary by individual art unit and are not predictions about the outcome of any particular application. They serve as a historical reference only.

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 Annan Q Shang 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: 919 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.
