Analysis

Hassan A Hussein is an examiner assigned to Tech Center 2400 and Art Unit 2431. The examiner has 143 resolved cases, providing a solid statistical foundation for understanding their prosecution patterns. This volume of 143 cases allows for a confident assessment of the examiner's typical outcomes and the effectiveness of different prosecution tactics.

The data shows an allowance rate of 60.1 percent. This 60.1 percent rate is reached over a median of 1105 days to allowance. Practitioners should anticipate a prosecution timeline of approximately 1105 days when working with this examiner. The moderate allowance rate suggests that while success is common, it often requires a persistent effort over several years.

The most notable figure for this examiner is the interview lift of 52.5 percent. This exceptionally high lift indicates that interviews are nearly essential for a successful outcome. A 52.5 percent increase in the probability of allowance following an interview is a strong signal that practitioners should seek direct dialogue. In Art Unit 2431, leveraging this 52.5 percent lift is likely the most effective way to improve upon the 60.1 percent base allowance rate.
