What the data says.reading this examiner

Examiner Atta Khan maintains a public record across one art unit in Technology Center 2400. Over hundreds of decided applications, Khan's allowance rate stands at 87%. This rate reflects the proportion of applications that have reached a final decision—either allowed or abandoned—and does not include pending applications. The allowance rate is pooled across all art units under Khan's examination authority and represents the examiner's historical record on decided cases.

How to read these numbers.

This profile aggregates Khan's record across multiple art units into a single pooled figure. The 87% allowance rate describes past decisions on applications that have concluded—allowed or abandoned. Aggregate statistics reflect historical performance and are not predictions about any specific application. Individual art-unit records, where available separately, may show variation from the pooled figure.

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 Atta Khan 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: 453 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.
