Analysis

Sang Cheon Lee examines cases in Tech Center 4100 and Art Unit 2462. The data includes 45 resolved cases, resulting in an allowance rate of 53.3 percent. A standout figure is the interview lift of 40.0 percent, which is exceptionally high. This suggests that interviews are a critical component of successful prosecution with this examiner.

The median days to allowance is 1293. This represents the time required to navigate the 53.3 percent allowance path. With only 45 resolved cases, the data set is smaller than others in this profile group, but the 40.0 percent interview lift remains a compelling reason to engage the examiner directly.

Practitioners should note the 1293 median days to allowance when setting client expectations. The allowance rate indicates a balanced outcome, but the lift from interviews suggests that the examiner is very responsive to oral advocacy. In Art Unit 2462, this examiner's resolved cases provide a snapshot of a prosecution style where direct communication significantly alters the likelihood of success.
