Analysis

Stella Eun Higgs is assigned to Tech Center 3600 and Art Unit 2141, where she has handled 365 resolved cases. Her allowance rate is 39.2%, which is a critical figure for practitioners to consider when assessing the difficulty of obtaining a grant. This lower rate is accompanied by a median days to allowance of 1381, indicating a challenging and lengthy prosecution environment. These two figures together suggest that applicants must be prepared for rigorous examination and multiple rounds of office actions.

Despite the 39.2% allowance rate, the interview lift pct of 34.2% offers a strategic opening for applicants. This lift shows that interviews are a powerful mechanism for overcoming rejections and improving the chances of success. Given the 1381 median days to allowance, early intervention through an interview may be necessary to avoid a protracted stay in Art Unit 2141. The 365 resolved cases provide a robust dataset for concluding that an interview is a vital component of a successful strategy with this examiner.
