Analysis

Masud K. Khan is an examiner in Tech Center 2100 and Art Unit 2131, with 455 resolved cases. He has a high allowance rate of 87.5 percent and a relatively short median days to allowance of 867. This profile indicates a very efficient and applicant-friendly prosecution environment, where nearly nine out of ten cases result in a grant.

The interview lift is 6.8 percent. Although the 87.5 percent baseline allowance rate is already very high, the positive lift indicates that interviews still provide a marginal benefit. Practitioners can expect a high likelihood of grant within the 867-day timeframe, and interviews can be used to fine-tune claims or address minor examiner concerns without delaying the process significantly.

Strategy for this examiner should focus on maintaining the efficiency shown by the 867 median days to allowance. The 87.5 percent allowance rate suggests that most applications are on a path to success. The 6.8 percent interview lift is a useful option for resolving any specific objections that might arise, ensuring a smooth path to patent issuance.
