Analysis

Alexander J. Yi operates in Art Unit 2617 within Tech Center 4100. He has 469 resolved cases and an allowance rate of 68.4 percent. The median time to allowance for these cases is 1223 days, indicating a prosecution cycle that exceeds three years. The 68.4 percent allowance rate shows a better than average chance of securing a grant in this art unit.

The most striking metric is the interview lift of 55.7 percent. This high figure suggests that interviews are exceptionally effective at moving applications toward allowance. Given the long median pendency of 1223 days, early and frequent communication with the examiner may be the most efficient path to a grant. The 55.7 percent lift is one of the highest in the tech center, making the interview a critical component of any prosecution strategy. With 469 resolved cases, the examiner's data strongly supports the use of verbal negotiation to overcome rejections. Practitioners should leverage this high lift to improve their 68.4 percent baseline probability.
