Analysis

Examiner Larry D. Riggs II works in Tech Center 4100 and Art Unit 1631. The examiner has 480 resolved cases, which provides a significant amount of data for practitioners to review. The allowance rate is 46.3%, indicating that fewer than half of the cases result in a grant. This 46.3% rate suggests a rigorous examination process in this art unit.

The interview lift is 32.5%. This is a substantial figure, indicating that interviews are a highly effective strategy for increasing the probability of an allowance. The 32.5% lift suggests that direct communication can be a turning point in the prosecution of an application assigned to this examiner.

The median days to allowance is 1584. This duration is a key metric for managing client expectations regarding the timeline for a successful outcome. In Art Unit 1631, the 480 resolved cases establish a clear pattern of behavior. Given the 46.3% allowance rate and the 1584-day median pendency, practitioners should consider the 32.5% interview lift as a primary tool for improving their results.
