Analysis

Examiner Hannah Sarah Philipose is assigned to Tech Center 1600 and Art Unit 1600. The examiner's current record includes 1 resolved case, which provides a limited but specific view into their prosecution history. This resolved case resulted in an allowance rate of 0.0 percent, indicating that the application did not reach a grant. For this specific instance, the median days to allowance is recorded as 1270, establishing a data point for the duration of the prosecution process under this examiner's review.

The data also shows an interview lift of 0.0 percent. Because the examiner has an allowance rate of 0.0 percent, the impact of interviews on the final outcome cannot be fully assessed through these figures alone. Practitioners should observe the 1270 days to allowance as the primary time-based metric available. While the 0.0 percent allowance rate is based on a sample size of 1 resolved case, it remains the current baseline for Art Unit 1600. Future cases may provide more context beyond the resolved cases currently documented.
