Analysis

Victor L. MacArthur has extensive experience in Tech Center 3700 and Art Unit 3618, with 1082 resolved cases. The examiner maintains an allowance rate of 66.3 percent, which offers a predictable outlook for applicants. This success rate is achieved with a median days to allowance of 1108, providing a benchmark for the duration of the prosecution cycle. These figures reflect a steady examination environment where approximately two-thirds of applications reach a grant after 1108 days of prosecution effort.

The interview lift is recorded at 12.8 percent, which adds value to the baseline 66.3 percent allowance rate. This indicates that while the written record is often sufficient for a grant, interviews remain a productive tool for resolving outstanding issues. With a sample of 1082 resolved cases, the 1108-day median pendency is a reliable data point for practitioners. In Art Unit 3618, the data suggests that a consistent prosecution strategy, supplemented by targeted interviews, is the most effective path to maintaining the 66.3 percent allowance probability.
