Analysis

Mariela D. Reyes, an examiner in Tech Center 2100 and Art Unit 2100, has overseen 347 resolved cases. Her allowance rate of 61.1% indicates a moderate level of success for applicants, with a majority of cases resulting in a grant. This rate provides a clear baseline for practitioners to assess the likelihood of a positive outcome when their applications are under her review.

The median days to allowance is 1601, which is a notably long timeframe for the prosecution process. This duration suggests that reaching a grant may require significant time and persistence. The data also shows an interview lift of 23.7%, indicating that the probability of allowance increases substantially when an interview is conducted, offering a way to improve upon the 61.1% baseline rate.

With 347 resolved cases, the 23.7% interview lift is a statistically relevant factor for strategy. The 1601-day median duration is a key consideration for managing client expectations. Practitioners should consider interviews as a means to potentially expedite the process or increase the chances of success in what appears to be a lengthy examination cycle in Art Unit 2100.
