Analysis

Frank Wei Min Lu is an examiner in Art Unit 1634 of Tech Center 1700. Across 711 resolved cases, the examiner maintains an allowance rate of 62.7 percent. This rate suggests a fair probability of success for applicants, with more than six out of ten cases resulting in a grant. Practitioners can use the 62.7 percent figure to benchmark their prosecution strategy in this unit.

The interview lift is 67.7 percent. This exceptionally high lift indicates that interviews are a vital component of a successful prosecution strategy. Practitioners should leverage the 67.7 percent lift to overcome rejections, as it represents one of the most significant benefits of verbal engagement seen in the data. The high lift suggests that direct communication is highly effective at resolving the examiner's concerns.

The median days to allowance is 1502. This is a long timeline, suggesting that the path to a grant often takes over four years. Given the 62.7 percent allowance rate and the 67.7 percent interview lift, persistent engagement and early interviews may be necessary to navigate the 1502-day median pendency. These metrics provide a comprehensive view of the time and tactics required for success.
