Analysis

Hong Thi Yoo is an examiner in Tech Center 1700, Art Unit 1621. She has 754 resolved cases with an allowance rate of 45.8 percent. The median time to reach an allowance is 1269 days. The 45.8 percent allowance rate indicates a challenging environment where less than half of the applications are granted.

The interview lift is 26.0 percent. This indicates that interviews are a valuable tool for improving the chances of success, which is 45.8 percent overall. Given the long median pendency of 1269 days, practitioners should consider early interviews to address examiner concerns and potentially improve the likelihood of a grant. The 26.0 percent lift is a significant factor that can help overcome the initial difficulty of prosecution. With 754 resolved cases, the data provides a clear picture of the benefits of direct communication. Navigating the 1269-day timeline requires a strategic use of the interview process to improve the odds of success. The 26.0 percent lift is a strong incentive for verbal engagement.
