// READING THIS EXAMINER

What the data says.

Jung-Mu T Chuang maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security), spanning one art unit. Across 356 disposed applications, 187 received allowance and 169 were abandoned, yielding a 53% allowance rate. This rate is calculated from decided applications only and does not reflect pending filings. The record reflects the examiner's aggregate activity across their assigned art unit(s) and represents historical data without bearing on any individual case.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates all applications decided by the examiner across their art unit(s) in TC 2100. The allowance rate reflects past outcomes pooled from that portfolio and describes what has occurred, not what will occur in a specific application. Aggregate figures mask variation within and across art units; a separate section on this page provides art-unit-level detail. Historical rates are correlational data and do not predict individual application outcomes.

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 Jung-Mu T Chuang 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: 356 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.
