Analysis

Holly Michaela Kipouros is a patent examiner currently serving in Tech Center 2800 and Art Unit 1631. Over the course of their career, this examiner has reached a final decision on 534 resolved cases. This total includes all applications that have been either granted as patents or abandoned by the applicants. This history of 534 resolved cases provides a statistical foundation for understanding the examiner's decision-making patterns within Art Unit 1631 and Tech Center 2800.

The data shows an allowance rate of 69.5 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 1083. This duration represents the middle point of the timeline for successful cases, meaning that the prosecution process often requires a commitment of 1083 days to reach a favorable conclusion. This 69.5 percent allowance rate is a critical metric for managing applicant expectations.

Furthermore, the interview lift is 21.6 percent. This 21.6 percent lift indicates the increase in the probability of receiving a grant when an interview is conducted compared to the baseline allowance rate of 69.5 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.
