This caseload provides a sufficient basis for evaluating his examination patterns in the fields of transportation and electronic commerce. His work in Art Unit 3636 involves navigating complex legal and technical issues, and his 239 cases offer a clear picture of his approach.

The examiner has a relatively low allowance rate of 28.0 percent. This suggests a challenging environment for applicants. However, he offers a significant interview lift of 28.9 percent. This high lift is a critical statistic, as it indicates that interviews are extremely effective at improving the chances of allowance. In fact, the 28.9 percent lift is larger than the 28.0 percent base allowance rate, highlighting the vital importance of direct communication with this examiner.

The median days to allowance for his cases is 1012. This timeframe indicates a standard prosecution duration. Given the low 28.0 percent allowance rate, practitioners must be prepared for a difficult path. The 28.9 percent interview lift should be considered an essential part of the strategy for any application on his docket. Utilizing an interview may be the single most important factor in overcoming the low base allowance rate within the 1012-day median window.
