What the data says.reading this examiner

Examiner Shawn S An maintains a pooled allowance rate of 68% across hundreds of decided applications in Technology Center 2400, art unit 2483. This allowance rate represents the share of applications that were allowed among all decided applications (allowed and abandoned combined), excluding pending matters. The examiner's record spans a single art unit within the technology center. The 68% figure is the examiner's historical allowance rate across their pooled decided caseload and does not constitute a prediction for any specific pending application.

How to read these numbers.

This pooled record aggregates all decided applications across the examiner's assigned art units. The 68% allowance rate describes past dispositions of applications that reached a final decision—allowed or abandoned—and excludes applications still pending. Aggregate historical statistics describe an examiner's overall record and are not predictions about the outcome of any individual application or the probability of allowance in any specific case.

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 Shawn S An 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: 744 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.
