Analysis

Derick J. Holzmacher is an examiner in Art Unit 3623, part of Tech Center 3600. He has overseen 281 resolved cases, providing a moderate sample size for performance analysis. His allowance rate of 44.5 percent suggests a more rigorous examination environment where less than half of applications reach a grant.

Given the lower allowance rate, the interview lift of 28.4 percent becomes a crucial strategic lever. This significant increase in the likelihood of allowance following an interview suggests that verbal advocacy is particularly impactful for applications assigned to this examiner. Practitioners may find that the 28.4 percent lift justifies the additional resources required for an interview compared to the 44.5 percent baseline.

The median days to allowance for these cases is 1132. This metric offers a temporal baseline for how long a successful prosecution typically lasts under his review. For the 281 resolved cases, this pendency figure helps set realistic milestones for the patent lifecycle in Tech Center 3600.
