Analysis

Mary C. Hibbert is an examiner in Tech Center 3700 and Art Unit 3721. The examiner has 307 resolved cases and an allowance rate of 66.4%. This rate suggests a favorable environment, with many cases reaching issuance. The median days to allowance is 1399, which provides a benchmark for the expected duration of the prosecution cycle from filing to grant.

The data reveals an interview lift of 26.5%. This 26.5% lift indicates that conducting an interview is effective and significantly improves the chances of allowance. Given the 66.4% allowance rate, an interview can be a helpful factor in overcoming rejections. Practitioners should consider direct communication to leverage this 26.5% boost and potentially shorten the 1399-day median pendency.

In Art Unit 3721, the 307 resolved cases provide a solid dataset for strategic planning. The combination of a 66.4% allowance rate and a 26.5% interview lift suggests that the examiner is open to verbal advocacy. Attorneys should use the 1399-day timeline to set client expectations while prioritizing interviews to improve the probability of a favorable outcome for their applications.
