What the data says.

Examiner Li P Sun has a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning 2 art units. Across 193 disposed applications, 93 were allowed and 100 were abandoned, yielding an allowance rate of 48%. This pooled figure represents the examiner's historical record across all assigned art units and reflects the proportion of decided applications that resulted in allowance. The record does not include pending applications.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates the examiner's work across multiple art units within TC 2100. The 48% allowance rate describes the examiner's historical performance across all assigned art units combined and is a summary of past dispositions. Aggregate figures describe what has occurred, not what will occur in any specific application. Individual art units may have different allowance rates; per-art-unit detail appears separately.

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 Li P Sun 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: 193 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.
