Analysis

Maria Teresa T. Thein works in Tech Center 3600, Art Unit 3625, with 222 resolved cases. The allowance rate is 28.4%. The interview lift is 32.1%, and the median days to allowance is 1675.

The 28.4% allowance rate indicates a difficult prosecution environment. However, the 32.1% interview lift is a significant positive factor, suggesting that interviews are effective at this desk. The 1675 days median pendency is quite long, reflecting a slow path to grant. Practitioners should be prepared for a long-term effort and should consider requesting an interview to improve the 28.4% baseline allowance rate. With 222 resolved cases, the examiner has an established history of rigorous examination. The 32.1% lift is one of the most actionable metrics in this profile, providing a strategy for overcoming the low allowance rate. The 1675 days median pendency requires a patient approach to prosecution in Art Unit 3625. These figures provide a basis for strategic planning in Tech Center 3600.
