This examiner grants 27% of resolved cases

Analysis

Examiner Ilse I Immanuel handles cases in Tech Center 3600 and Art Unit 3685. The data shows a total of 316 resolved cases with an allowance rate of 27.2 percent. This low rate indicates a highly restrictive examination environment. Additionally, the median days to allowance is 1546, which points to a long and potentially difficult path for applicants seeking to secure a patent grant in this art unit.

Despite the challenging 27.2 percent allowance rate, examiner interviews offer a significant advantage. The interview lift is 27.5 percent, which provides a substantial increase in the likelihood of success compared to the baseline. For the 316 resolved cases, this lift is a highly impactful tool available to practitioners. Given the 1546-day median pendency, initiating an interview early in the process may be essential to navigate the hurdles present in Art Unit 3685 and improve upon the 27.5 percent lift statistic.
