Analysis

Amir Elsayed Darwish is an examiner in Tech Center 4100, assigned to Art Unit 2187. He has a small sample size of 12 resolved cases. Despite this limited history, the data reveals a 50.0% allowance rate. The most significant metric is the 75.0% interview lift, which suggests that interviews are extremely effective at moving cases toward allowance.

The median days to allowance for this examiner is 1530. This duration indicates a very long prosecution process, likely involving complex issues or multiple office actions. For practitioners, the 12 resolved cases mean that while the 50.0% allowance rate is a useful starting point, the 75.0% interview lift is the most actionable piece of data. In Art Unit 2187, the 1530-day median pendency suggests that applicants should be prepared for a slow process, but direct communication is a vital tool.
