This examiner grants 78% of resolved cases

Analysis

Scott J. Walthour has overseen 663 resolved cases in Art Unit 3632 of Tech Center 3700. The examiner's allowance rate is 78.4 percent, providing a stable and generally favorable environment for patent applicants. This 78.4 percent rate indicates that the examiner is open to finding allowable subject matter and that most applications will eventually reach a grant after proper prosecution.

The median days to allowance is 962, showing a relatively efficient prosecution timeline that stays below the thousand-day mark. An exceptionally high interview lift of 70.0 percent suggests that verbal communication is a critical tool for resolving issues and securing an allowance. This 70.0 percent lift is one of the most significant positive correlations between interviews and grants in the data.

Practitioners should consider an interview mandatory if they face any rejections, as the 70.0 percent lift can dramatically change the prospects of an application. The 962 day median suggests that this examiner is capable of moving cases quickly once technical issues are resolved. Combining the 78.4 percent baseline with a strategic interview is the most effective way to ensure a successful outcome.
