Analysis

Hwei-Min Lu serves in Tech Center 4100 and Art Unit 2122. The examiner has 240 resolved cases and an allowance rate of 63.3 percent. This 63.3 percent rate reflects the level of difficulty for the unit. The median days to allowance is 1083, providing a specific timeline for applicants to anticipate when seeking a grant.

The interview lift is 40.2 percent, which is a substantial increase over the baseline. This 40.2 percent lift suggests that interviews are highly effective at moving cases toward allowance. Given the 240 resolved cases, this metric is a reliable indicator that verbal communication can significantly improve prosecution results. The 63.3 percent allowance rate is a strong foundation that is further bolstered by these interactions.

In Art Unit 2122, the 1083-day median pendency can be navigated more successfully by employing the 40.2 percent interview lift. Practitioners should prioritize interviews with Hwei-Min Lu to leverage this advantage. These figures from Tech Center 4100 offer a clear strategic path for securing patent rights based on the 240 resolved cases.
