Analysis

Shirley V. Gembeh is a highly active examiner in Tech Center 1700 and Art Unit 1615, with 1640 resolved cases. The allowance rate is 63.2%, which is a moderate rate that suggests a fair chance of success for applicants. This rate indicates that more than half of the applications are eventually granted under this examiner's review.

The interview lift is 34.0%, which is a very high figure. This indicates that interviews are an extremely powerful tool for applicants to use when working with this examiner to secure an allowance. The substantial lift suggests that oral advocacy is far more effective than written correspondence alone in resolving issues and moving the application toward a grant.

The median days to allowance is 968. This duration is consistent with other examiners in the same tech center, representing a typical timeframe for patent prosecution of under three years. The combination of a moderate allowance rate and a very high interview lift makes oral advocacy a critical strategy for success.
