Analysis

Patricia L. Hailey, an examiner in Art Unit 1629 and Tech Center 4100, shows an allowance rate of 88.2% across 1285 resolved cases. This rate of approval indicates a favorable environment for applicants seeking patent protection in this specific area. The efficiency of the process is further reflected in the median time to allowance, which stands at 874 days. Practitioners should view the 88.2% allowance rate as a strong indicator of success in Art Unit 1629.

While the baseline allowance rate is high, the interview lift of 10.1% provides a measurable benefit for those who choose to engage directly with the examiner. With 1285 resolved cases, the data suggests a consistent and predictable examination style. The 874 days to allowance is relatively swift, and the 10.1% lift suggests that while interviews are not strictly necessary for success, they can still assist in navigating the final stages of prosecution. This examiner maintains a high volume of resolutions while keeping pendency within a predictable range.
