Analysis

Cathleen R Hutchins is a high-volume examiner in Tech Center 3600, specifically Art Unit 3672. With 1146 resolved cases, the examiner has one of the most extensive records available. This volume of 1146 cases provides a very high level of statistical confidence in the associated metrics. The data reveals an allowance rate of 83.9 percent, suggesting a very favorable environment for applicants.

The median time to allowance is 918 days. This 918-day timeline indicates a relatively efficient process, especially given the high volume of cases handled. Practitioners can expect a high probability of success within this 918-day median timeframe. The 83.9 percent allowance rate is a stable and reliable baseline for any application assigned to this examiner in Art Unit 3672.

The interview lift is 7.9 percent. This 7.9 percent lift is relatively low, likely because the base allowance rate is already quite high. In a docket where 83.9 percent of cases are allowed, there is less room for an interview to provide a massive statistical boost. However, the 7.9 percent lift still offers a marginal benefit. Overall, the 1146 resolved cases point to a predictable and successful prosecution path in Tech Center 3600.
