Analysis

Peter J. Macchiarolo is an examiner in Tech Center 2800 and Art Unit 2855, with a record of 284 resolved cases. The data shows an allowance rate of 70.1 percent, which indicates the likelihood of success for applicants. This rate is paired with a median days to allowance of 1168, providing an expectation for the duration of the prosecution cycle. These metrics suggest a stable examination environment where approximately seven out of ten applications reach a grant after 1168 days of prosecution effort.

The interview lift is recorded at 10.8 percent, which provides an increase to the 70.1 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 284 resolved cases, the 1168-day median pendency is a reliable data point for practitioners. In Art Unit 2855, the data suggests that a consistent prosecution strategy, supplemented by targeted interviews, is an effective path to maintaining the 70.1 percent allowance probability.
