// READING THIS EXAMINER

What the data says.

Examiner Yahao Chen has a public record spanning one art unit in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 82 disposed applications, the examiner allowed 24 and abandoned 58, yielding an allowance rate of 29%. This rate reflects the ratio of allowed to decided applications in the pooled record and does not predict outcomes in any individual case. The record covers a single art unit, making it a straightforward profile of historical decisions in TC 2100 without aggregation across multiple areas of practice.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates decisions across one art unit within TC 2100. The 29% allowance rate describes what happened in the examiner's decided caseload—it is a historical summary, not a forecast of any pending or future application. Pooled rates reflect past output across the unit(s) listed and are correlational, not causal. They do not indicate how any examiner will act on a specific claim or amendment.

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 Yahao 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: 82 applications.
