Analysis

Lewis Alexander Bullock Jr. serves in Tech Center 2400 and Art Unit 2100. He has 79 resolved cases, with an allowance rate pct of 31.6. This indicates that a minority of the applications he reviews result in a patent grant. The median days to allowance for these successful cases is 1743, which reflects a long timeframe for the prosecution process in his unit from filing to grant.

The interview lift pct of 44.8 is a standout metric. It indicates that interviews are effective and correlate with an increase in the probability of allowance. In Art Unit 2100, the 44.8 interview lift pct suggests that oral advocacy is a critical tool for overcoming rejections and improving the 31.6 allowance rate pct from the 79 resolved cases. This lift is a strong indicator of examiner receptivity.

The 31.6 allowance rate pct and the 1743 median days to allowance define a challenging landscape for applicants. However, the 44.8 interview lift pct provides a mechanism for improving outcomes. Practitioners should use the 79 resolved cases as a guide, utilizing interviews to navigate Tech Center 2400 and move toward a successful allowance. The 1743 median days to allowance is the primary timing guide.
