Analysis

Amy M. Bunker works in Tech Center 1600 and Art Unit 1612. She has 505 resolved cases, with an allowance rate pct of 29.1. This indicates that a minority of the applications she reviews result in a patent grant. The median days to allowance for these successful cases is 1425, which reflects a long timeframe for the prosecution process in her unit from filing to grant.

The interview lift pct of 45.5 is a standout metric. It indicates that interviews are effective and correlate with an increase in the probability of allowance. In Art Unit 1612, the 45.5 interview lift pct suggests that oral advocacy is a critical tool for overcoming rejections and improving the 29.1 allowance rate pct from the 505 resolved cases. This lift is a strong indicator of examiner receptivity.

The 29.1 allowance rate pct and the 1425 median days to allowance define a challenging landscape for applicants. However, the 45.5 interview lift pct provides a mechanism for improving outcomes. Practitioners should use the 505 resolved cases as a guide, utilizing interviews to navigate Tech Center 1600 and move toward a successful allowance. The 1425 median days to allowance is the primary timing guide.
