Analysis

Justin Matthew Larson has processed 1266 resolved cases in Tech Center 4100. His allowance rate pct of 56.5% in Art Unit 3612 suggests a more rigorous examination environment than some peers. This rate indicates that just over half of the applications on his docket reach a final grant, requiring a focused prosecution strategy.

Interviews are a highly impactful tool for applicants working with this examiner. The interview lift pct of 22.8% demonstrates that verbal advocacy significantly improves the chances of overcoming rejections. Given the 56.5% baseline allowance rate, the substantial lift from interviews makes direct engagement one of the most effective tactics available to practitioners.

The median_days_to_allowance is 891. Despite the lower allowance rate, the relatively shorter pendency to allowance suggests that when Larson does approve a case, he does so with reasonable speed. Practitioners should use the 22.8% interview lift to navigate the 56.5% allowance environment efficiently within this 891-day timeframe.
