Examiner: SINGH, RUPANGINI

Tech Center 3600 • Art Units: 3628

This examiner grants 35% of resolved cases

Analysis

Rupangini Singh has resolved 260 cases in Art Unit 3628. The 35.4% allowance rate is relatively low, suggesting a challenging environment for applicants in Tech Center 3600. This rate indicates that practitioners must be highly prepared to address examiner objections through multiple office actions.

The median days to allowance is 1430, reflecting a lengthy prosecution process. However, the interview lift pct of 52.2% is very high, indicating that interviews are a vital strategy for overcoming examiner objections. This significant lift suggests that direct communication can effectively bridge the gap between a rejection and a grant. For applications assigned to Art Unit 3628, scheduling an interview early in the process may be the most efficient way to navigate the examiner's rigorous standards and secure an allowance. The data clearly shows that while the base probability of success is low, the impact of an interview is substantial.
