Analysis

Esther Benoit Henderson is an examiner in Art Unit 2142, part of Tech Center 2400. She has a substantial track record with 690 resolved cases. Her allowance rate is 79.1 percent, which is a high metric indicating a favorable environment for applicants. This 79.1 percent rate suggests that she is frequently able to find allowable subject matter, making her an accessible examiner in her field. The 690 resolved cases provide a reliable data set for analyzing her prosecution patterns.

The interview lift for this examiner is 23.3 percent. Even with a high baseline allowance rate of 79.1 percent, the data shows that interviews provide a significant additional boost to the probability of success. This 23.3 percent lift suggests that direct engagement is highly effective in her cases, potentially resolving any remaining issues and leading to a grant. Practitioners should leverage this lift to maximize their chances of a favorable outcome in Art Unit 2142.

However, the median days to allowance is 1326. This is a relatively long timeline for Tech Center 2400, indicating that while success is likely, the process can be slow. Applicants should be prepared for a pendency of 1326 days. The combination of a 79.1 percent allowance rate and a 1326-day median pendency suggests a thorough but ultimately successful prosecution experience for most applicants. The 1326-day duration is a critical factor for managing client expectations.
