Examiner: WALKER, CHRISTOPHER RICHARD

Analysis

Christopher Richard Walker has handled 144 resolved cases in Art Unit 2855 of Tech Center 3600. The examiner maintains an allowance rate of 72.9 percent, providing a stable environment for patent applicants. This 72.9 percent rate indicates that nearly three out of four applications reach a grant, suggesting a reasonable path to issuance for those who meet the examiner's requirements.

The median days to allowance is 998, keeping the prosecution timeline just under the thousand-day mark. This 998 day median is a useful benchmark for managing client expectations regarding the duration of the examination process. An interview lift of 18.3 percent indicates that verbal communication provides a helpful boost to the probability of grant, though the baseline rate is already strong.

Practitioners should consider an interview if they encounter difficult rejections, as the 18.3 percent lift shows a clear benefit to direct engagement. While the 72.9 percent allowance rate is favorable, the interview can help clarify technical points and potentially speed up the 998 day timeline. Overall, the data suggests a predictable and manageable prosecution experience with this examiner.
