Tech Center 4100 • Art Units: 1629 1645 4100

This examiner grants 60% of resolved cases

Analysis

William Justin Youngblood works in Art Unit 1629 of Tech Center 4100. He has 75 resolved cases and an allowance rate of 60.0 percent. The median days to allowance is 1210. The 60.0 percent allowance rate indicates a moderate level of success for applicants reaching a final resolution.

The interview lift is 41.7 percent. This high lift suggests that interviews are very effective for this examiner. Given the 60.0 percent baseline allowance rate and a median pendency of 1210 days, practitioners should prioritize interviews to address rejections and potentially shorten the prosecution timeline. The 41.7 percent lift is a strong indicator that the examiner is highly responsive to verbal discussion. With 75 resolved cases, the data shows a clear benefit to direct communication. Applicants should prepare for a long prosecution cycle of 1210 days and use interviews as a primary tool to resolve outstanding issues. This strategy can significantly improve the chances of a grant beyond the 60.0 percent baseline.
