Analysis

Yonghong Li, assigned to Tech Center 3600 and Art Unit 3648, has completed 221 resolved cases. The allowance rate of 76.5 percent is relatively high, suggesting that the examiner frequently finds ways to allow applications. This rate provides a positive outlook for practitioners working within this specific art unit. The median days to allowance of 1104 indicates that while the probability of success is high, the process requires a steady commitment. This 1104-day figure is a key data point for managing client expectations.

The data highlights an interview lift of 22.0 percent, which serves as a valuable tool for overcoming rejections. This lift suggests that verbal discussions can clarify technical nuances that might be missed in written correspondence. With 221 resolved cases, the examiner's trends are well-defined, showing a clear preference for resolution through both standard prosecution and interviewed cases. Practitioners should factor the 76.5 percent allowance rate into their strategy while utilizing the 22.0 percent lift to optimize their chances of success. The 1104-day median remains the primary timeline benchmark.
