// READING THIS EXAMINER

What the data says.

Mandrita Brahmachari maintains a pooled allowance rate of 76% across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner's record spans 3 art units. Across these art units, allowance rates range from 63% to 83%. This pooled figure represents the share of applications that were allowed among all decided applications (allowed and abandoned), and reflects the examiner's historical record across the breadth of the technology center's subject matter.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates statistics across multiple art units into a single overall figure. The 76% allowance rate and the 63%–83% range are summaries of past decisions and do not function as predictions for any specific pending application. Pooled data shows the examiner's overall pattern but masks variation among individual art units; detailed per-unit rates appear in a separate section of this page.

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 →

// BY ART UNIT

The record, art unit by art unit.

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 & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Mandrita Brahmachari 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 July 14, 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: 458 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.
