This examiner grants 64% of resolved cases

Analysis

Russell E Sparks manages a docket in Tech Center 1700 and Art Unit 1700, with 399 resolved cases. The allowance rate of 63.4% suggests a moderate to high probability of success for applicants. However, the median days to allowance of 1276 indicates that the process often extends over a significant period. The 399 resolved cases provide a robust sample for understanding this examiner's tendencies.

The interview lift of 14.8% provides a helpful boost to the 63.4% allowance rate. While the examiner is already somewhat likely to grant a patent, the 14.8% lift shows that interviews are a viable tactic for overcoming specific hurdles. With 399 resolved cases, these figures provide a reliable baseline for expectations in this art unit. Practitioners should plan for the 1276 days of pendency while keeping the 14.8% lift in mind as a tool to improve the 63.4% chance of allowance. Direct engagement can help clarify technical issues and potentially shorten the path to a grant. The data suggests that verbal communication is a valuable supplement to written prosecution.
