// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates data across all art units assigned to the examiner. The allowance rate of 58% describes historical outcomes on decided applications and serves as a statistical summary of past dispositions. Aggregate figures do not predict the outcome of any specific application, nor do they account for variations in application complexity, subject matter within the technology center, or individual prosecution histories. These statistics offer context on the examiner's overall record 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 Longbit Chai 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: 163 applications.

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.
