Analysis

Arthur D. Duran is an examiner in Tech Center 3600, working within Art Unit 3621. He has managed 443 resolved cases. This volume of work provides a solid foundation for analyzing his examination style in the fields of transportation and electronic commerce. His experience level suggests a consistent approach to the technical and legal requirements of his specific art unit.

The examiner has a very low allowance rate of 15.8 percent. This indicates an exceptionally challenging environment for applicants. However, he shows a significant interview lift of 23.6 percent. This high lift is a critical statistic, as it indicates that interviews are very effective at improving the chances of allowance. Given the low 15.8 percent base rate, the 23.6 percent lift represents a substantial relative increase in the probability of securing a grant through direct communication.

The median days to allowance for his cases is 2078. This is an extremely long timeline, indicating a very slow prosecution process. The combination of a 15.8 percent allowance rate and a 2078-day median suggests a very difficult path to grant. Practitioners should consider the 23.6 percent interview lift as an essential tool for navigating this prolonged timeline. Utilizing an interview may be the most effective way to improve the low likelihood of success within the 2078-day window.
