// READING THIS EXAMINER

What the data says.

Alan S Chen maintains a 90% allowance rate across more than a thousand decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His record spans four art units: 2124, 2125, 2129, and 2182. The allowance rate—the share of decided applications that were allowed rather than abandoned—ranges from 84% to 95% across these art units. This pooled figure aggregates his activity across all four units and reflects the historical outcome distribution for applications he has decided.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's performance across multiple art units, creating a single overall allowance rate. This aggregate is a historical summary, not a prediction for any individual application. The range (minimum to maximum allowance rate by art unit) shows variation in outcomes across different subject areas the examiner handles. Understanding both the overall rate and its spread provides context for the examiner's past record, though each application's disposition depends on its specific claims, 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 →

// 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 Alan S Chen 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: 1,728 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.
