What the data says.reading this examiner

Cheng-Feng Huang maintains a public record in Technology Center 2400, spanning a single art unit. Across hundreds of decided applications, the examiner's allowance rate is 89%. This figure represents the percentage of applications that were allowed among all decided applications (allowed and abandoned combined), excluding pending matters. The allowance rate is derived from the examiner's pooled record and reflects historical disposition patterns. The record covers applications within one art-unit classification, providing a consolidated view of examination outcomes in this technology area.

How to read these numbers.

A pooled record aggregates examination outcomes across all of an examiner's art units into a single allowance-rate figure. This percentage reflects what occurred in past decided cases and does not constitute a prediction for any specific pending application. The allowance rate describes historical patterns only. Individual applications may be influenced by claim scope, prior art, specification adequacy, and other case-specific factors not captured in aggregate statistics. Pooled data serves as background context on an examiner's overall record.

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 Cheng-Feng Huang

  • What is Cheng-Feng Huang's overall allowance rate?
    The examiner's allowance rate is 89% across hundreds of decided applications. This represents the share of decided cases (allowed plus abandoned) that resulted in allowance. It is a historical measure and not a prediction of any specific application.
  • How many art units does this examiner work in?
    Cheng-Feng Huang's record covers one art unit within Technology Center 2400. The pooled figures aggregate all outcomes within that unit.
  • What does the allowance rate include or exclude?
    The allowance rate includes only decided applications—those that were allowed or abandoned. Pending applications are excluded. The rate does not include withdrawn, suspended, or other non-final dispositions.
  • Can I use this allowance rate to predict my application's outcome?
    No. The allowance rate is a historical aggregate and does not predict the outcome of any specific application. Individual case outcomes depend on claim scope, prior art, specification adequacy, and other application-specific factors.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Cheng-Feng Huang 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: 641 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.
