What the data says.reading this examiner

Han Yang's public record in Technology Center 2400 spans one art unit and covers hundreds of decided applications. Across that pooled set, the allowance rate is 91%. This figure represents the percentage of applications that were allowed, as a share of all decided applications (allowed and abandoned combined), excluding pending cases. The allowance rate does not forecast outcomes in any individual case and reflects the examiner's historical record only.

How to read these numbers.

This pooled record aggregates data across all art units under which the examiner has issued decisions. The allowance rate of 91% describes past dispositions across decided applications and is not a prediction about any specific application. Aggregate figures mask variation across art units and do not indicate how any particular case will be examined or decided. The data reflects correlation only and carries no causal implication.

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 →

  • How many art units does this record cover?
    The record spans one art unit within Technology Center 2400.
  • Does this rate predict what will happen to my application?
    No. The allowance rate describes past dispositions only and is not a prediction of any specific application's outcome.
  • What does this pooled record show?
    It aggregates the examiner's decision history across all art units under which decisions were issued. Aggregate statistics do not reveal variation within individual art units or circumstances of particular cases.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Han Yang has a public record within Technology Center 2400. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 22, 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: 322 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.
