Analysis

Khai Quynh Tien Pham is an examiner in Art Unit 1637 within Tech Center 1600. The current data is based on 1 resolved case, which resulted in an allowance rate of 0.0 percent. This resolution also reflects an interview lift of 0.0 percent. For applications that reach allowance, the median time is 1214 days. These figures represent a limited sample size, but they establish the initial baseline for prosecution timelines and outcomes in this specific art unit.

Practitioners should monitor how these metrics evolve as more cases are resolved. The 0.0 percent allowance rate and 1214-day median pendency suggest a cautious approach to prosecution in the early stages of this examiner's tenure. Without more data, the lack of a recorded interview lift should be viewed as preliminary rather than a definitive indicator of the effectiveness of oral advocacy in Art Unit 1637. This baseline provides a starting point for evaluating the examiner's approach to patentability and procedural efficiency.
