// READING THIS EXAMINER

What the data says.

Examiner Li P Sun maintains a pooled allowance rate of 48% across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). This rate reflects the share of applications that resulted in allowance among all decided (allowed and abandoned) applications, pooled across the examiner's 2 art units. The public record spans art units 2143 and 2176. The allowance rate is a historical measure of past dispositions and does not predict outcomes for any individual application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates applications across multiple art units within TC 2100, combining different subject-matter areas into a single allowance-rate figure. Aggregate statistics describe past outcomes only and are not predictive of any specific application's disposition. Individual art units may show different rates; a separate section of this page displays per-art-unit detail for comparison.

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.

  • What does the allowance rate measure?
    The allowance rate is the percentage of decided applications (allowed plus abandoned, excluding pending) that were allowed. It reflects past outcomes and does not indicate the outcome of any pending or future application.

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 July 14, 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.

Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

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.
