Analysis

Examiner Sam M. Refai operates in Tech Center 3600 and Art Unit 3621. The examiner has 439 resolved cases. The allowance rate is 34.9%. This 34.9% allowance rate indicates a challenging prosecution environment where about one-third of the applications result in a grant. Practitioners should use this 34.9% baseline to prepare for a potentially rigorous examination process.

The interview lift is 7.4%. This 7.4% lift is a positive value, though it is smaller than the 34.9% allowance rate. This indicates that while an interview can provide an increase in the chances of allowance, the impact is more modest than in other dockets. The 7.4% interview lift is still a tool for practitioners who need to address specific examiner concerns or clarify claim language during the 1318 median days to allowance.

The median days to allowance is 1318. This 1318-day figure represents the median time for cases to reach allowance under this examiner. With 439 resolved cases, the 1318-day metric and the 34.9% allowance rate provide a consistent outlook for prosecution. Applicants can use the 1318 median days to allowance to plan their timelines in Art Unit 3621, while considering the 7.4% interview lift as a tactical option.
