Analysis

Kyu Hyung Han serves as an examiner in Art Unit 2123 within Tech Center 2100. The examiner has 16 resolved cases and an allowance rate of 43.8 percent. This dataset, while based on 16 cases, offers a look into the examiner's tendencies in the computer memory or data processing fields. The 43.8 percent rate indicates that fewer than half of the applications reach a grant, suggesting a rigorous examination process.

The median days to allowance for these cases is 1521. This is a substantial amount of time, and practitioners should prepare for a long prosecution cycle when assigned to this examiner. The 1521-day figure serves as a benchmark for the time required to reach a successful outcome in Art Unit 2123. Understanding this timeline is crucial for managing patent term adjustments and client expectations.

The interview lift is 36.7 percent. This high percentage suggests that interviews are a powerful tool for increasing the probability of an allowance. For the 16 cases resolved, the 36.7 percent lift indicates that direct engagement with the examiner can significantly improve the 43.8 percent baseline allowance rate. Practitioners should consider a formal interview as a primary strategy to overcome rejections and move applications toward a final grant.
