What the data says.reading this examiner

Peian Lou maintains a public record in Technology Center 2400 spanning one art unit. Across dozens of decided applications, the examiner's allowance rate is 89%. This rate represents the share of applications that issued as allowed among all decided applications (allowed and abandoned combined), excluding pending cases. The allowance rate is derived from the examiner's pooled record and reflects historical outcomes in disposed cases.

How to read these numbers.

This pooled record aggregates decided applications across all art units where the examiner has worked. The allowance rate of 89% describes the examiner's past record—the proportion of decided applications that were allowed. An aggregate figure does not predict the outcome of any individual application or indicate how any specific case will be examined. Pooled data represents historical disposal patterns, not forward-looking guidance.

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 →

Questions about Examiner Peian Lou

  • What is Peian Lou's overall allowance rate?
    The examiner's allowance rate is 89% across dozens of decided applications. This is the percentage of applications that issued as allowed among all applications that were decided (allowed or abandoned), pooled across all art units in the examiner's record.
  • How many art units does this examiner cover?
    Peian Lou's public record spans one art unit within Technology Center 2400. This pooled profile aggregates all decided applications across that art unit.
  • What does an 89% allowance rate mean?
    An 89% allowance rate means that of all applications decided (allowed or abandoned), 89% resulted in allowance. This is a historical statistic and is not a prediction of the outcome of any pending or future application.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Peian Lou 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: 70 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.
