Analysis

Chad Andrew Reverman, an examiner in Tech Center 2800 and Art Unit 2858, has overseen 72 resolved cases. His allowance rate of 58.3% indicates a moderate level of difficulty, with a majority of his cases resulting in a grant. This baseline provides a starting point for applicants to assess their chances of success during the examination process.

The median days to allowance is 1073, which indicates a prosecution timeline that typically extends for a significant period. A key finding in the data is the interview lift of 44.8%. This substantial increase in the likelihood of allowance following an interview suggests that direct communication is an effective strategy for overcoming objections and reaching a positive conclusion in Art Unit 2858.

With 72 resolved cases, the 44.8% interview lift is a compelling reason for practitioners to prioritize interviews. When compared to the 58.3% baseline allowance rate, the impact of an interview is very significant. Applicants should use the 1073-day median duration as a planning tool, while relying on the high interview lift to improve their overall prospects for success.
