// READING THIS EXAMINER

What the data says.

Examiner Chongsuh Park maintains a public record across two art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 114 disposed applications, the examiner's pooled allowance rate is 61%, based on 69 allowed and 45 abandoned applications. The allowance rate ranges from 46% to 65% across the examiner's art units, reflecting variation in outcomes between the different areas of examination within TC 2100. This pooled figure represents the examiner's aggregate record and describes past decisions only.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines results from multiple art units into a single aggregate profile. The overall allowance rate (61% here) is the average outcome across all the examiner's art units combined, not a prediction of any specific application's fate. The range (46% to 65%) shows that allowance rates differ among the examiner's art units; the pooled rate sits between those extremes. Pooled figures describe historical performance and do not forecast outcomes for individual cases.

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 Chongsuh Park 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: 114 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.
