This examiner grants 91% of resolved cases

Analysis

Examiner S M Sohel Imtiaz works within Tech Center 4100 and Art Unit 1787. The examiner has a high allowance rate of 90.7 percent across 560 resolved cases. This suggests that the vast majority of applications in this portfolio successfully reach issuance. The median days to allowance is 843, providing a clear timeframe for applicants to expect a final decision on their patent filings.

While the allowance rate is already high, the interview lift is 7.0 percent. This relatively small lift indicates that while interviews are helpful, they may not be the primary driver of success in this unit. For the 560 resolved cases, the 90.7 percent allowance rate demonstrates a high probability of grant regardless of interview status. Practitioners in Art Unit 1787 should focus on maintaining the quality of their submissions to align with the 843-day median pendency and the 7.0 percent lift potential.
