Analysis

Christopher B. Tokarczyk is an examiner in Art Unit 3622 of Tech Center 3600. He has 332 resolved cases and an allowance rate of 43.7 percent. This 43.7 percent rate suggests a rigorous examination process where less than half of the resolved cases result in a patent grant. This figure provides a baseline for practitioners to evaluate their chances.

However, the interview lift is 23.7 percent. This 23.7 percent lift indicates that interviews are an effective tool for increasing the chances of allowance. Practitioners should consider scheduling an interview, as this lift can improve the baseline 43.7 percent allowance rate and help resolve outstanding issues for the 332 resolved cases.

The median days to allowance is 1216. This 1216-day timeframe provides a benchmark for the duration of the prosecution process in Art Unit 3622. With 332 resolved cases, the 1216-day median and the 23.7 percent interview lift are metrics for developing a strategy when working with Tokarczyk.
