Analysis

Matthew Thomas Largi operates within Tech Center 3700 and Art Unit 2858, where he has managed 700 resolved cases. His overall allowance rate of 76.9% suggests a relatively high frequency of successful outcomes for applicants. This rate provides a strong baseline for those entering prosecution, indicating that more than three out of four cases reach a grant.

The data indicates that conducting an interview is a productive strategy with this examiner. The interview lift pct of 15.7% shows that cases involving an interview are more likely to reach allowance than those without. This lift is significant enough that practitioners should prioritize verbal communication to resolve potential rejections early in the process.

Efficiency in reaching these outcomes is reflected in the median_days_to_allowance of 917. This duration provides a clear expectation for the timeline of a successful application. When planning a strategy in Art Unit 2858, the combination of a 76.9% allowance rate and a 15.7% interview lift suggests that active engagement can lead to both favorable and relatively timely results.
