This examiner grants 40% of resolved cases

Analysis

Examiner Crum presents a challenging path in Art Unit 1613, with an allowance rate of 40.4% across 94 resolved cases. This suggests a rigorous examination process in Tech Center 1600. The median days to allowance of 1322 further highlights the difficulty, showing a very long timeline. These metrics, based on 94 resolved cases, indicate that securing a patent requires both persistence and a high level of technical justification.

However, the interview lift of 65.0% is exceptionally high. This suggests that for the 94 resolved cases, an interview was almost always necessary to achieve an allowance. Given the low 40.4% baseline allowance rate and the long 1322-day median pendency, an interview is an essential and highly effective tool for any applicant assigned to this examiner. The 65.0% lift is a clear signal that the examiner is extremely responsive to verbal arguments and collaborative problem-solving. Utilizing this tool is the most effective way to navigate the 1322-day timeline and improve the probability of success in this rigorous art unit.
