Tech Center 4100 • Art Units: 2448 2458 4100

This examiner grants 73% of resolved cases

Analysis

Examiner Cox has handled 454 resolved cases in Art Unit 2448, achieving an allowance rate of 72.9%. This rate indicates a generally positive outlook for applicants in Tech Center 4100. However, the median days to allowance of 1166 shows that the path to a grant is often lengthy. The 454 resolved cases provide a solid foundation for understanding the examiner's balanced but time-intensive approach to prosecution.

The interview lift of 21.4% is a significant strategic indicator. It suggests that for the 454 resolved cases, an interview was a highly effective way to accelerate the process or overcome examiner concerns. Given the 1166-day median pendency, applicants should consider an early interview to potentially shorten the timeline and capitalize on this high lift percentage. The 21.4% lift is among the more substantial benefits seen in this tech center, making it a primary tool for practitioners. By combining the 72.9% allowance rate with a proactive interview strategy, applicants can significantly improve their chances of a favorable and more timely resolution.
