Analysis

Olivia Walker is assigned to Art Unit 3700 within Tech Center 3700 and has 14 resolved cases in her profile. The examiner maintains an allowance rate of 35.7 percent, which is quite low and indicates a challenging environment for those seeking patent protection. This 35.7 percent rate suggests that the examiner is highly critical of the applications they review, requiring significant effort to reach a grant.

Successful prosecution with this examiner takes a median of 1026 days to allowance. This 1026 day duration suggests that even when a grant is achieved, the process is likely to be thorough and time-consuming. Practitioners should plan for a rigorous examination that may last around 1026 days, ensuring that their clients are prepared for the potential for multiple rounds of rejections.

The most striking data point is the interview lift of 75.0 percent. This 75.0 percent lift suggests that interviews are an essential tool for navigating this examiner's requirements. Direct verbal engagement is significantly more likely to result in an allowance than relying solely on written responses, making it a mandatory strategy for anyone hoping to overcome the low 35.7 percent baseline allowance rate.
