Analysis

Chad G. Erdman examines cases in Tech Center 3700 and Art Unit 1759, with 578 resolved cases. His allowance rate is 80.1 percent. The median time to allowance for these cases is 926 days. This 926 days figure suggests a predictable and relatively efficient timeline for obtaining a patent grant from this examiner.

The data shows an interview lift of 18.0 percent. This indicates that interviews are effective at further increasing the already high 80.1 percent allowance rate. For the 578 cases resolved by this examiner, an interview is a statistically sound strategy for securing a patent grant. The 18.0 percent lift provides a meaningful advantage for practitioners who choose to engage in direct discussion. With an 80.1 percent allowance rate, the baseline for success is already high, and the 18.0 percent lift further solidifies the chances of a positive outcome. The 926 days median pendency is a key benchmark for prosecution planning.
