Analysis

Han V Doan, working in Art Unit 2136 of Tech Center 2100, has handled 186 resolved cases. The examiner demonstrates a high allowance rate of 80.6 percent. The median days to allowance is 1080, which defines the expected timeline for prosecution from filing to a successful conclusion.

For the 186 resolved cases, the combination of a high allowance rate and a strong interview lift suggests that proactive communication is highly effective.
