// READING THIS EXAMINER

What the data says.

Yemane Mesfin maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across one art unit, the examiner has disposed of 101 applications. Of those decided applications, 71 were allowed and 30 were abandoned, yielding an allowance rate of 70%. This figure represents the proportion of applications that received approval among all applications that reached a final disposition—either allowance or abandonment. The record reflects work across a single art unit within TC 2100.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates data across all art units in which the examiner works. The 70% allowance rate describes the historical proportion of allowed versus abandoned applications already decided. Pooled figures do not account for variation by art unit or application type and are not a prediction of the outcome of any specific pending or future application. Review of the examiner's per-art-unit breakdown, where available, may provide additional context.

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 →

// BY ART UNIT

Questions about Examiner Yemane Mesfin

  • What is Yemane Mesfin's overall allowance rate?
    The examiner's allowance rate is 70% across 101 disposed applications in Technology Center 2100, calculated as allowed applications divided by total decided applications (allowed plus abandoned).
  • How many art units does this examiner cover?
    This examiner works in one art unit (2144) within TC 2100. The pooled figures shown here aggregate the examiner's entire record across that single unit.
  • What do these statistics predict about my application?
    These figures describe the examiner's historical record only. They are not a prediction of any specific application's outcome and do not account for differences in technology, claim scope, prior art, or individual prosecution history.
  • Does a 70% allowance rate mean I have a 70% chance of allowance?
    No. The 70% rate is a past aggregate only. It reflects proportions across 101 already-decided cases and does not predict the result of any particular pending application.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Yemane Mesfin 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 June 25, 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: 101 applications.

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.
