Tech Center 1700 • Art Units: 1638 1765 1796
This examiner grants 55% of resolved cases
Rabon A. Sergent has a high volume of experience in Tech Center 1700 and Art Unit 1638, with 1005 resolved cases. The allowance rate is 55.0%, indicating a balanced approach to examination. However, the prosecution timeline is relatively long, with a median of 1310 days to allowance.
A key takeaway for practitioners is the 24.1% interview lift. This high lift suggests that interviews are particularly effective at moving cases toward a grant, potentially overcoming the hurdles that lead to the 55.0% baseline. For the 1005 cases handled, the 1310-day median underscores the need for a strategic approach that includes early and frequent communication. The 24.1% lift is a significant metric for navigating this art unit successfully. Practitioners should prioritize interviews.
