Analysis

Aileen Baker Felton is an examiner in Tech Center 1700 and Art Unit 1624, with 449 resolved cases. Her allowance rate is 51.9 percent. This rate shows a balanced outcome for applicants, with roughly half of the cases resulting in an allowance. The 51.9 percent allowance rate suggests that success depends heavily on the technical merits and the quality of the prosecution strategy.

The interview lift is 16.5 percent. This positive lift suggests that engaging in an interview can meaningfully improve the chances of an application being allowed.
