Analysis

Examiner Taeyoon Kim operates within Tech Center 1600 and is assigned to Art Unit 1631. Throughout their tenure, they have managed 896 resolved cases, which represents the total number of patent applications that have reached a final resolution. These 896 resolved cases offer a comprehensive view of the examiner's work within Art Unit 1631 and Tech Center 1600.

The records indicate an allowance rate of 51.5 percent, showing the proportion of cases that result in a patent grant. The median days to allowance for these successful applications is 1381. This 1381 days duration serves as a benchmark for the expected length of the prosecution process. The 51.5 percent allowance rate provides a clear expectation for applicants seeking a grant.

A significant factor in this examiner's profile is the interview lift of 52.1 percent. This 52.1 percent lift represents the increase in the likelihood of allowance when an interview is held compared to the baseline rate. Given the typical timeline for successful cases, the 52.1 percent interview lift suggests that direct communication is a highly effective tactic for improving prosecution outcomes.
