What the data says.reading this examiner

Jason Chung maintains a public record in Technology Center 2400 spanning 1 art unit. Across hundreds of decided applications, his allowance rate is 76%. This rate represents the share of applications in his pooled record that were allowed, as a proportion of all decided applications (allowed and abandoned combined). The record reflects outcomes on applications that have reached a final disposition; pending applications are excluded from this calculation.

How to read these numbers.

This pooled record aggregates all of the examiner's decided applications across his art units. The overall allowance rate of 76% describes his past outcomes and does not constitute a prediction of what will occur on any specific application. Pooled figures combine different areas of patent subject matter and reflect historical performance only. Individual art units may have different rates; those appear in separate sections of this page.

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 Jason Chung

  • What is Jason Chung's overall allowance rate?
    His allowance rate is 76% across hundreds of decided applications in Technology Center 2400. This is the percentage of decided applications (allowed plus abandoned) that were allowed.
  • How many art units does this record cover?
    This pooled record spans 1 art unit. The examiner's work in TC 2400 is consolidated in this profile.
  • Does the allowance rate predict the outcome of my application?
    No. The pooled allowance rate describes historical outcomes on decided applications and is not a prediction of any specific application's disposition. Individual cases depend on claim scope, prior art, and prosecution history.
  • What does 'decided applications' mean?
    Decided applications are those that have reached a final disposition—either allowed or abandoned. Pending applications are excluded from the allowance-rate calculation.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Jason Chung 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: 155 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.
