Analysis

Kris E. Mackes is an examiner in Tech Center 2100 and Art Unit 2153, with a record of 540 resolved cases. The data shows an allowance rate of 76.1 percent, which indicates the likelihood of success for applicants. This rate is paired with a median days to allowance of 1072, providing an expectation for the duration of the prosecution cycle. These metrics suggest a stable examination environment where approximately three-quarters of applications reach a grant after 1072 days of prosecution effort.

The interview lift is recorded at 10.9 percent, which provides an increase to the 76.1 percent baseline allowance rate. This indicates that while the written record is often sufficient, interviews remain a useful tool for resolving any remaining technical disputes. With 540 resolved cases as a foundation, the 1072-day median pendency is a reliable data point for practitioners. In Art Unit 2153, the data suggests that a consistent prosecution strategy, supplemented by targeted interviews, is the most effective path to maintaining the 76.1 percent allowance probability.
