What the data says.

Chun Cao holds a public record across 3 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 1,453 disposed applications, the examiner's allowance rate is 85%. The record spans art units 2115, 2182, and 2185. Of 1,497 total applications, 1,232 were allowed and 221 were abandoned. This pooled figure aggregates decisions across all three art units and reflects the examiner's historical record. The allowance rate describes past outcomes only and is not a prediction of any specific application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates data across multiple art units, creating a single profile from heterogeneous examination populations. The allowance rate (85%) and application counts reflect cumulative decisions and do not predict outcomes in any individual case. Pooled figures mask variation by art unit; separate art-unit data may show different patterns. Aggregate statistics describe what occurred historically, not what will occur in future prosecution.

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 Chun Cao 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: 1,497 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.
