What the data says.reading this examiner

Examiner Chandrahas B Patel maintains a pooled allowance rate of 90% across more than a thousand decided applications in Technology Center 2400. His record spans 2 art units. The allowance rate ranges from 47% to 91% across these art units, reflecting variation in outcomes by subject area within the technology center. This pooled figure represents the examiner's aggregate record and describes applications that have been decided—either allowed or abandoned—and excludes pending applications.

How to read these numbers.

A pooled record aggregates decided applications across multiple art units, providing a single summary metric of past outcomes. The overall allowance rate reflects the examiner's combined history and is not a prediction of any specific application's outcome. Variation across individual art units is common; the range shown here reflects differences in subject matter and application characteristics within each art unit, not changes in examination approach over time.

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 Chandrahas B 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: 1,091 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.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes. Where this page compares an examiner's allowance rate to an art-unit average, that comparison is a factual description of the public record, not a characterization of any individual examiner's conduct or competence.
