What the data says.reading this examiner

Sumitra Ganguly maintains a record across one art unit within Technology Center 2400. Across hundreds of decided applications, the examiner's allowance rate is 82%. This figure reflects the share of decided applications (those allowed or abandoned) in the pooled record and does not include pending applications. The allowance rate represents the examiner's historical disposition of applications that have reached a final determination. This statistic describes the past record and is not predictive of outcomes in any individual application.

How to read these numbers.

This profile aggregates the examiner's record across a single art unit. The allowance rate is a historical measure—a snapshot of decided applications already closed. Aggregate figures describe patterns in past decisions and are not forecasts for any specific case. Different applications present different claim scope, prior art, and procedural circumstances. A pooled allowance rate alone does not determine the path any pending application will take.

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 Sumitra Ganguly 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: 253 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.
