This history of 976 resolved cases provides a statistical foundation for understanding the examiner's decision-making patterns within Art Unit 3733 and Tech Center 3700.

The data shows an allowance rate of 50.6 percent, which reflects the frequency with which applications are successfully prosecuted to a grant. For those applications that achieve an allowance, the median days to allowance is 1161. This duration represents the middle point of the timeline for successful cases, meaning that the prosecution process often requires a commitment of 1161 days to reach a favorable conclusion. This 50.6 percent allowance rate is a critical metric for managing applicant expectations.

Furthermore, the interview lift is 34.4 percent. This 34.4 percent lift indicates the increase in the probability of receiving a grant when an interview is conducted compared to the baseline allowance rate of 50.6 percent. The relationship between the allowance rate and the interview lift suggests that direct engagement with the examiner is a productive strategy. Practitioners may find that this lift is a vital tool for navigating the typical prosecution timeline.
