Analysis

Justin Ye Lee is an examiner in Tech Center 2600 and Art Unit 2415. He has a high volume of 714 resolved cases, making his performance metrics statistically significant. His allowance rate is 80.1 percent, which suggests a high probability of success for patent applicants. This 80.1 percent rate places him among the approachable examiners in his tech center.

The interview lift for this examiner is 11.0 percent. While the baseline is already high, the 11.0 percent lift indicates that interviews still provide a meaningful advantage. Practitioners should consider whether the additional effort of an interview is warranted given the high initial allowance rate. However, the 714 resolved cases show that he is experienced and likely has established preferences for how cases are presented in Art Unit 2415.

The median days to allowance is 1164. This timeline indicates that prosecution under his review typically takes a considerable amount of time. Applicants should factor this 1164-day median into their long-term intellectual property strategies. Despite the 1164-day duration, the high allowance rate suggests that the majority of persistent applicants will ultimately receive a grant.
