This examiner grants 90% of resolved cases
Joseph Chang, an examiner in Tech Center 2800 and Art Unit 2817, shows a high allowance rate of 89.8 percent across 1191 resolved cases. This high rate of approval suggests that most applications reaching a final disposition under his review result in a grant. The 89.8 percent allowance rate is a strong indicator of a receptive approach to patentability in Art Unit 2817.
The prosecution timeline is relatively efficient, with a median days to allowance of 709. This 709-day figure is an important benchmark for applicants planning their patent strategy. While the interview lift is 3.9 percent, the overall high success rate may reduce the perceived necessity for such interventions. However, even a 3.9 percent lift can be decisive in close cases among the 1191 resolved cases.
Practitioners should note that the 1191 resolved cases provide a substantial data set for predicting outcomes in Art Unit 2817. The efficiency shown by the 709-day median and the 89.8 percent allowance rate makes this examiner's docket a predictable one for applicants. This predictability is valuable for managing long-term intellectual property portfolios.
