What the data says.reading this examiner

Sharmin Chowdhury maintains a public record in Technology Center 2400 across one art unit. Over hundreds of decided applications in the examiner's pooled record, the allowance rate stands at 89%. This figure represents the share of applications that were allowed among all decided applications (allowed and abandoned combined), excluding pending matters. The allowance rate is based on historical outcomes and describes past decisions only.

How to read these numbers.

This pooled record aggregates the examiner's outcomes across all art units in TC 2400. The 89% allowance rate describes historical decisions on applications that reached a final disposition. Pooled figures represent past performance and are not predictions of how any specific application will be examined or decided. Individual art-unit records may differ from the overall aggregate.

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 Sharmin Chowdhury 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: 387 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.
