Analysis

Daniel Duc Tran is an examiner in Art Unit 2145 within Tech Center 2100, with a record of 4 resolved cases. The current allowance rate is 0.0 percent, and the interview lift is also a matching value, which reflects the outcomes for applications in this area. The median days to allowance is 1130 days, providing a baseline for the time required to reach a final disposition. This 1130-day period is a factor for practitioners to consider when setting expectations for prosecution.

The data for the 4 resolved cases shows that verbal communication has not yet resulted in a change in outcomes. When compared to the allowance rate of 0.0 percent, the lack of lift suggests that initial cases have faced significant hurdles. For the applications processed in Art Unit 2145, the examination process has not yet led to a grant. Practitioners should evaluate their approach within Tech Center 2100 accordingly.

In summary, the allowance rate and 1130-day median to allowance define the current profile for this examiner. The 4 resolved cases provide the only available data points for Art Unit 2145. While the interview lift indicates no historical benefit from interviews, the small number of cases suggests that the profile is still developing within Tech Center 2100.
