Analysis

Tirone Derek Johnson is assigned to Art Unit 1600 in Tech Center 1600. The data shows 1 resolved case, which resulted in an allowance rate of 0.0 percent. This limited sample size may not fully reflect the examiner's long-term trends or typical behavior. Practitioners should view these initial results as a single data point for understanding the examiner's approach in this specific art unit.

The interview lift is also 0.0 percent. This matches the allowance rate, as the single resolved case did not result in a grant. In this specific instance, an interview did not lead to an allowance. However, with only 1 resolved case on record, it is premature to conclude that interviews are ineffective. Applicants may still find value in direct communication to explore the examiner's specific technical concerns.

The median days to allowance is 1189. This duration is based on the limited data available and provides a single reference point for pendency. To navigate a process that may last 1189 days, practitioners should focus on building a robust record. While the 0.0 percent allowance rate is based on minimal data, it underscores the importance of a thorough and well-supported application from the outset.
