Tech Center 1700 • Art Units: 1729 1752
This examiner grants 72% of resolved cases
Osei K. Amponsah, in Art Unit 1729 within Tech Center 1700, has resolved 710 cases. The allowance rate is 72.4%, and the median days to allowance is 1211. This suggests a reasonable chance of success but a lengthy process for applicants. The 1211-day median pendency is a significant factor to account for in the overall patent strategy.
The interview lift is 33.1%, showing that interviews are highly effective at moving cases toward a grant. This lift is a significant factor for practitioners to consider, as it can substantially improve the 72.4% base allowance rate. With 710 resolved cases, the data indicates that the examiner is very responsive to personal engagement. Practitioners should prioritize interviews to address rejections and potentially shorten the 1211-day timeline. The 33.1% lift represents one of the stronger strategic advantages available in this art unit.
