Analysis

Ram N. Kackar is an examiner within Tech Center 2600 and Art Unit 1711, having managed 517 resolved cases. The examiner maintains an allowance rate of 40.2 percent, which reflects the standard that applications must meet.

A feature of this examiner's profile is the interview lift of 57.9 percent, which is higher than the 40.2 percent allowance rate. This figure demonstrates that engaging in direct dialogue with the examiner is an effective strategy, increasing the likelihood of a grant compared to cases without an interview. Given the 517 resolved cases of experience, the 57.9 percent interview lift suggests that rejections can be addressed through verbal clarification. Practitioners should use interviews to navigate the 1435-day median pendency and improve their chances within Art Unit 1711.
