Examiner Chameli Das has allowed 796 of 883 decided applications (90%) in Computer Architecture, Software, and Information Security.
Examiner Chameli Das maintains a pooled allowance rate of 90% across 883 disposed applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner's record spans four art units: 2122, 2192, 2196, and 2197. Of the 883 decided applications, 796 were allowed and 87 were abandoned. The allowance rate across these art units ranges from 74% to 94%, reflecting variation in outcomes within the examiner's portfolio. This pooled figure aggregates the examiner's decisions across all assigned art units and represents the historical record only.
A pooled record aggregates allowance rates across multiple art units, masking variation within each unit. The overall 90% figure describes past decisions on 883 applications but is not a prediction for any specific case. Individual art units may show different rates. Pooled statistics are useful for understanding an examiner's general record but do not forecast the outcome of any single application or indicate how an examiner will treat particular claims or arguments.
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 →
Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.

Methodology. This page pools every art unit in which Examiner Chameli Das has a public record within Technology Center 2100. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated June 25, 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: 883 applications.

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.
