Analysis

Calvin L. Hewitt II examines applications in Tech Center 3600 and Art Unit 3623. The data shows 70 resolved cases with an allowance rate of 1.4%. This extremely low percentage suggests a very challenging environment for applicants. Practitioners must be prepared for rigorous examination and a high likelihood of abandonment, as only 1.4% of cases have reached allowance. The median days to allowance is 1927, indicating a very long prosecution timeline for the few cases that succeed.

The interview lift is 6.0%. While this 6.0% lift is positive, it remains relatively low, suggesting that verbal communication only slightly improves the chances of overcoming the 1.4% allowance rate. The 1927-day figure is a critical planning metric for budgeting and strategy. In Art Unit 3623, navigating a docket with 70 resolved cases and such a low allowance rate requires a specialized approach.

The 6.0% interview lift may be one of the few tools available to move a case forward, though the 1927-day median pendency suggests that even successful outcomes take significant time. Applicants should evaluate the value of their claims against these 1.4% odds. With 70 cases resolved, these metrics provide a clear warning about the difficulty of prosecution with this examiner.
