// READING THIS EXAMINER

What the data says.

Examiner Chih Ching Chow maintains a pooled allowance rate of 82% across 255 disposed applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). This rate is calculated from 209 allowed applications and 46 abandoned applications. The examiner's record spans three art units: 2122, 2191, and 2192. Allowance rates across these art units range from 80% to 83%, reflecting variation in outcomes by art unit. This pooled figure represents the examiner's historical record and is not a prediction of outcomes for any individual application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates allowance data across multiple art units, masking differences in outcomes among individual units. The 82% figure describes what occurred across all three art units combined over the examiner's history, not what will occur on any pending or future application. Allowance rates vary by art unit (80% to 83% here), so applicants examining this examiner's per-art-unit breakdown may observe different rates in the specific unit handling their application. Pooled data is historical context only.

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 Chih Ching Chow 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: 255 applications.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
