Analysis

Si Ming Ku serves as an examiner in Art Unit 3771 within Tech Center 3700. The examiner has 774 resolved cases, resulting in an allowance rate of 72.7 percent. This rate indicates a generally favorable environment for applicants, with a consistent pattern of granting patents.

The data highlights an interview lift of 32.8 percent, suggesting that direct engagement is an effective factor in resolving objections. This 32.8 percent lift shows that interviews can improve the chances of allowance compared to written prosecution alone. The median days to allowance is 1139, reflecting the typical duration of the prosecution process. Practitioners should factor the 1139-day median into their strategy. Given the 72.7 percent allowance rate and the impact of interviews, practitioners have a clear incentive to use verbal communication to navigate the examination process effectively in Art Unit 3771.
