// READING THIS EXAMINER

What the data says.

Yu Zhao maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security), spanning one art unit. Across hundreds of decided applications, the examiner's allowance rate is 54%. This figure represents the percentage of applications that were allowed among all decided applications (allowed and abandoned combined), excluding pending matters. The 54% allowance rate describes the examiner's historical record in this technology center and reflects outcomes across the pooled set of decided cases.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile aggregates all decided applications across the examiner's art units in TC 2100. The allowance rate is a historical measure describing past outcomes among decided cases and is not a prediction of any specific application's outcome. Pooled figures mask variation across different art units and cannot be used to forecast results in a particular classification. Review the detailed per-art-unit breakdown separately to understand performance within a specific area.

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 Yu Zhao 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: 407 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.
