This examiner grants 86% of resolved cases

Analysis

Joseph S Wong examines applications in Tech Center 2800 and Art Unit 1737. He has a record of 575 resolved cases and a high allowance rate of 86.3 percent. This rate indicates a very favorable outlook for applicants. The median days to allowance for his cases is 779, which is a relatively fast timeline for reaching a patent grant.

The data shows an interview lift of 7.4 percent. While the 86.3 percent allowance rate is already high, the 7.4 percent lift suggests that interviews still provide a measurable benefit. For the 575 cases resolved, the combination of a high allowance rate and a 7.4 percent lift makes for a predictable prosecution environment. Practitioners can expect an efficient process, as evidenced by the 779-day median pendency, which is also likely to result in a grant.
