What the data says.

David J Pearson maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across dozens of decided applications pooled from his single art unit, the examiner's allowance rate is 41%. This figure represents the share of decided applications (allowed and abandoned combined) in which patents were allowed. The allowance rate describes the examiner's historical record and does not indicate the outcome of any particular pending application. Decided applications exclude pending matters.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates all art units under the examiner's jurisdiction. The allowance rate reflects past dispositions across multiple application types within TC 2100 and is descriptive only—a historical measure, not a prediction tool. Aggregate statistics describe broad patterns in closed matters and do not forecast the result of any specific application. Individual art units may show different patterns; consult the per-art-unit section for detail by specialty.

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 David J Pearson

  • What is David J Pearson's allowance rate?
    The examiner's allowance rate is 41% across dozens of decided applications in TC 2100. This is the percentage of decided applications (allowed and abandoned) in which allowances issued, and does not predict the outcome of any pending application.
  • How many art units does this examiner cover?
    David J Pearson's public record spans one art unit in Technology Center 2100 (Computer Architecture, Software, and Information Security).
  • Does this pooled rate apply to my application?
    No. The pooled allowance rate describes historical dispositions and is not a prediction of any specific application's outcome. Actual results depend on the claims, prior art, and examination history of the individual case.
  • What does 'decided applications' mean?
    Decided applications are those that have received 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 David J Pearson 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: 58 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.
