Analysis

Yana B. Krinker serves as an examiner in Art Unit 1741 within Tech Center 1700. The examiner has 439 resolved cases, resulting in an allowance rate of 58.5 percent. This rate indicates a balanced examination process where more than half of the applications reach a grant. The 439 resolved cases provide a clear statistical foundation for understanding the examiner's patterns and the general probability of success in this art unit.

The data highlights an interview lift of 32.2 percent, suggesting that direct engagement is a very effective factor in resolving objections. This 32.2 percent lift shows that interviews can significantly improve the chances of allowance compared to written prosecution alone. The median days to allowance is 1490, reflecting the typical duration of the prosecution process. Practitioners should factor the 1490-day median into their long-term strategy. Given the 58.5 percent allowance rate and the substantial impact of interviews, practitioners have a strong incentive to prioritize verbal communication to navigate the examination process effectively.
