Examiner: FERGUSON, KEITH

Analysis

Keith Ferguson is an examiner in Tech Center 2800 and Art Unit 2618, with 765 resolved cases. His allowance rate is 86.3 percent. This high rate indicates that most applications he handles result in a patent grant. The 86.3 percent allowance rate suggests a favorable environment for applicants, with a high degree of predictability in the outcome of the examination process.

The interview lift is 8.5 percent. This positive lift shows that interviews are beneficial, although the high baseline allowance rate of 86.3 percent suggests that many cases are allowed through written prosecution alone. For the 765 resolved cases, interviews provide a useful supplemental path to success. Practitioners can use the 8.5 percent lift to resolve any technical ambiguities that may arise.

The median days to allowance is 839. This timeframe indicates a relatively efficient prosecution process. Applicants can expect a high probability of allowance and a standard timeline, supported by the 86.3 percent allowance rate and the 8.5 percent interview lift. The 839-day median is a key benchmark for managing expectations regarding the duration of the prosecution cycle.
