// READING THIS EXAMINER

What the data says.

Ying Yu Chen maintains a public record across two art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner has disposed of 227 applications, of which 173 were allowed and 54 were abandoned. This yields an allowance rate of 76% over the decided applications. The examiner's record spans art units 2122 and 2125. These figures reflect the pooled outcome across both units and describe the historical record of dispositions.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile aggregates Chen's record across multiple art units in TC 2100. Pooled statistics combine different subject areas and examination practices into a single allowance rate and disposal count. An aggregate allowance rate describes what occurred in the past and does not function as a prediction for any individual application. The breadth of art units in this record means the figures represent outcomes across distinct technical domains.

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 Ying Yu Chen 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: 227 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.
