This examiner grants 24% of resolved cases

Analysis

Pan G. Choy operates in Tech Center 3600 and Art Unit 2129. The examiner has 467 resolved cases, providing a substantial basis for performance analysis. The allowance rate is 24.4 percent, indicating a challenging environment for applicants where a minority of cases result in a grant. This suggests a rigorous examination style or a particularly complex set of technologies within the unit.

Despite the low allowance rate, the interview lift is a significant 34.9 percent. This high figure indicates that interviews are an exceptionally effective way to overcome hurdles and secure an allowance. Practitioners should prioritize direct communication to improve their chances of success. However, the median days to allowance is 1711, which is a very long timeline. While the initial allowance rate is low, the 34.9 percent interview lift suggests that proactive advocacy can lead to a positive outcome, though it will likely take a significant amount of time within the 1711-day cycle.
