Analysis

Christopher D Birkhimer operates in Tech Center 2100 and Art Unit 2136. The examiner has 515 resolved cases and an allowance rate pct of 74.6. This provides a robust dataset for evaluating prosecution trends. The data suggests a generally favorable environment for applicants, with nearly three quarters of cases reaching allowance.

The median days to allowance is 1129. The interview lift pct is 7.6, suggesting that while interviews are helpful, the examiner's general allowance behavior is the primary driver of outcomes.

Overall, the data indicates a predictable prosecution path with a high probability of success and a moderate benefit from direct examiner engagement.
