Examiner: CRAIG, KAILA ANGELIQUE

Tech Center 3600 • Art Units: 1615 1618 3646

This examiner grants 34% of resolved cases

Analysis

Examiner Craig presents a difficult path for applicants in Art Unit 1615, with an allowance rate of only 33.8%. This low rate, based on 65 resolved cases, suggests a very rigorous examination standard in Tech Center 3600. The median days to allowance of 1310 further highlights the challenges, showing a very long timeline. These metrics indicate that applicants must be prepared for a long and potentially contentious prosecution process.

However, the interview lift of 25.2% is remarkably high. This suggests that for the 65 resolved cases, an interview was often the only way to move toward an allowance. Given the low 33.8% baseline allowance rate and the long 1310-day median pendency, an interview should be considered an essential part of the prosecution strategy. The 25.2% lift is a powerful indicator that direct communication can overcome the examiner's strict standards. Practitioners should use this data to advocate for early interviews to improve the probability of success and potentially shorten the 1310-day wait for a grant.
