What the data says.reading this examiner

Chirag R Patel maintains a public record in Technology Center 2400 spanning two art units. Across hundreds of decided applications, the examiner's allowance rate stands at 88%. This rate reflects the share of applications that were allowed among all decided applications in the pooled record. The allowance rate is computed from decided applications only—pending applications are excluded from this calculation. The record aggregates activity across multiple art units and represents the examiner's historical performance in those units.

How to read these numbers.

This profile presents a pooled record combining data from multiple art units within TC 2400. Aggregate figures describe past performance across all decided applications handled by this examiner and are not predictions of outcomes in any specific case. Individual art units may have different allowance rates; per-unit detail appears separately. An aggregate allowance rate reflects historical decisions but cannot be applied to forecast the result of any particular application.

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 Chirag R Patel 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: 829 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.
