Analysis

Nathan C. Zollinger has a substantial history of 877 resolved cases in Tech Center 3700. Operating within Art Unit 3616, the examiner maintains an allowance rate of 69.6 percent. This volume of cases provides a highly reliable data set for practitioners to evaluate prosecution strategies. The median days to allowance is 1037, which sets a clear expectation for the duration of the patent acquisition process.

The interview lift of 40.2 percent is a critical metric for this profile. This lift indicates that applications are significantly more likely to reach allowance when an interview is conducted. Given the 69.6 percent baseline allowance rate, the 40.2 percent increase suggests that direct communication is exceptionally effective in Art Unit 3616. With 877 resolved cases, the examiner's patterns are well-established. Practitioners should prioritize interviews to navigate the 1037 days of pendency and maximize the probability of a grant.
