What the data says.

Examiner Shangao Zhang maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 47 disposed applications, 21 were allowed and 26 were abandoned, yielding an allowance rate of 45%.

The allowance rate is computed from the pool of all decided cases and does not constitute a prediction for any particular application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates all of Examiner Zhang's decided applications within TC 2100 across all art units in which the examiner operates. The 45% allowance rate describes what occurred in the closed record and is a historical measure, not a forecast. Individual applications vary in complexity and claim scope. Pooled statistics do not predict the outcome of any specific case and reflect correlations in past data, not causation.

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 Shangao Zhang 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: 47 applications.

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.
