Examiner Lechi Truong has allowed 1,064 of 1,204 decided applications in Computer Architecture, Software, and Information Security.
Examiner Lechi Truong maintains a pooled record across more than a thousand decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner's allowance rate stands at 88% of those decided applications. The public record spans 2 art units within TC 2100. This pooled figure represents applications that have been allowed or abandoned; pending applications are excluded from the calculation. The allowance rate reflects the examiner's historical record across the covered art units and does not constitute a prediction for any specific application.
This profile aggregates the examiner's record across multiple art units in TC 2100. Pooled allowance rates combine all decided applications within those units and reflect past outcomes, not forecasts. Allowance and abandonment counts vary across individual art units, meaning the pooled figure masks variation between them. A pooled rate is useful context for an examiner's overall record but does not predict the outcome of any particular application or the handling of any specific art unit.
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 →
Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.
Primarily examines program control and execution.
Grounds can co-occur, so the four don't sum to 100%. The art-unit figure is the unweighted mean across examiners in the art unit; §102 and §112 carry no art-unit benchmark.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 759 decided applications with an interview and 438 without.
Primarily examines neural-network / biological-model computing, and machine learning.

Methodology. This page pools every art unit in which Examiner Lechi Truong 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: 1,255 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.
