Analysis

Jong Suk Lee serves in Tech Center 3600 and Art Unit 2875. He has handled 127 resolved cases, which provides a moderate sample size for evaluating his examination style. The allowance rate for this examiner is 18.1 percent. This 18.1 percent figure indicates that the majority of cases do not result in an immediate grant, requiring applicants to be persistent in their prosecution efforts.

Despite the allowance rate, the interview lift is significant at 27.9 percent. This 27.9 percent increase suggests that personal engagement is a highly effective strategy when working with this examiner. For practitioners facing the 18.1 percent baseline, an interview appears to be a necessary tool to improve the odds of success. The data implies that verbal communication may bridge gaps that written amendments cannot easily address. The 127 resolved cases reinforce the importance of this tactic.

The median days to allowance is 983. This timeline shows that even when a grant is achieved, the process typically spans a significant period. Applicants should prepare for a rigorous and potentially lengthy prosecution given the 983-day median. Navigating Art Unit 2875 under this examiner requires a proactive approach to overcome initial rejections.
