Analysis

Errol V Fernandes is an examiner in Tech Center 2800 and Art Unit 2821, with 821 resolved cases. His allowance rate is 85.4 percent. This high rate indicates a very favorable environment for patent applicants. The 85.4 percent allowance rate suggests that the vast majority of applications reaching a resolution result in a granted patent, providing a high level of predictability.

The interview lift is 10.8 percent. This positive lift shows that interviews are beneficial, although the high baseline allowance rate of 85.4 percent suggests that many cases are allowed through written prosecution alone. For the 821 resolved cases, interviews provide a useful supplemental path to success. Practitioners can use the 10.8 percent lift to address specific concerns and potentially expedite the grant process.

The median days to allowance is 799. This timeframe indicates an efficient prosecution process. Applicants can expect a high probability of allowance and a relatively fast timeline, supported by the 85.4 percent allowance rate and the 10.8 percent interview lift. The 799-day median is a key benchmark for managing expectations regarding the duration of the prosecution cycle.
