Analysis

Daniel Guang-Dian Chen, an examiner in Tech Center 4100, has a perfect allowance rate of 100.0% across 4 resolved cases. This rate in Art Unit 3612 indicates that every case handled by this examiner has resulted in an allowance. The median time to allowance is 924 days, providing a preliminary timeline for the prosecution process.

The interview lift is 0.0%, which is consistent with the 100.0% base allowance rate. Since all cases are allowed, an interview cannot further increase the probability of success. This 0.0% lift suggests that the examiner's standard process is already effective at reaching an allowance.
