// READING THIS EXAMINER

What the data says.

Examiner Chae M Ko maintains a pooled allowance rate of 91% across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). This rate represents the percentage of applications that were allowed or abandoned among all decided applications in the examiner's record. The examiner's practice spans one art unit. The allowance rate is calculated from the pool of decided applications and does not include pending applications. This figure is a historical summary of past dispositions and is not predictive of outcomes on any individual application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates applications across all of the examiner's assigned art units. The pooled allowance rate describes the examiner's historical record and reflects past outcomes across the full range of work. Aggregate figures summarize what has occurred, not what will occur in any particular case. A pooled rate across multiple art units reflects an overall pattern but does not determine the path of any single 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 →

// 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 Chae M Ko 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: 929 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.
