What the data says.reading this examiner

Sanjoy K Roy maintains a public record across 2 art units in Technology Center 2400. Over hundreds of decided applications pooled across these art units, the examiner's allowance rate stands at 71%. The allowance rate ranges from 68% to 84% across these art units. This pooled figure represents the share of applications that were allowed among all decided applications (allowed and abandoned combined) in the examiner's record. The range reflects variation in allowance rates among the individual art units where the examiner has maintained a substantial record.

How to read these numbers.

A pooled record aggregates data across multiple art units, creating an overall snapshot of examination outcomes. The 71% allowance rate is a historical statistic describing past decisions across decided applications and is not a prediction of any specific application's outcome. The range from 68% to 84% shows that allowance rates vary among the examiner's art units. Understanding pooled data as an aggregate—rather than as predictive for individual cases—provides context for how the examiner's record distributes across different technology areas.

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 Sanjoy K Roy 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: 241 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.
