Analysis

Matthew Walter Baca serves in Art Unit 2855 within Tech Center 4100, where he has resolved 126 cases. He maintains an allowance rate of 72.2%, which suggests a high likelihood of securing a patent for applicants.

The interview lift for Examiner Baca is 5.7% over the 72.2% baseline allowance rate, providing a slight advantage. While the lift is not transformative, it indicates that interviews can be useful for resolving specific sticking points in the claims. With 126 resolved cases, the examiner has established a consistent pattern of resolution within the 1050-day median window. Practitioners should consider an interview if written responses do not immediately lead to an allowance, as the positive lift suggests a willingness to engage even when the baseline success rate is already 72.2%.
