Analysis

Susan Emily Fernandez is an examiner in Tech Center 1600 and Art Unit 1651, with 562 resolved cases. Her allowance rate is 52.5 percent. This rate indicates that about half of the cases she resolves result in a patent grant. The 52.5 percent allowance rate suggests a balanced environment where success depends on the technical merits and the quality of the prosecution strategy.

The interview lift is 60.8 percent. This is an exceptionally high lift, suggesting that interviews are an extremely powerful tool for overcoming rejections. Given the 52.5 percent allowance rate, conducting an interview appears to be a critical step for practitioners looking to improve their chances of success. For the 562 resolved cases, the 60.8 percent lift is the most significant strategic lever available.

The median days to allowance is 1364. This timeline provides a benchmark for the duration of the prosecution process. With 562 resolved cases, the data highlights that while the allowance rate is moderate, the 60.8 percent interview lift offers a strong pathway to overcoming rejections. The 1364-day median should be factored into the overall prosecution strategy for this art unit.
