This examiner grants 60% of resolved cases
Yue Yin Choi handles cases in Tech Center 3600, specifically within Art Unit 3600. The examiner has managed 152 resolved cases to date, resulting in an allowance rate of 59.2 percent. This percentage reflects a moderate level of difficulty for applicants seeking patent protection in this technology area.
The interview lift for this examiner is 8.3 percent. While this indicates a positive correlation between interviews and allowances, the impact is less pronounced than in other art units. Practitioners may still find value in direct communication, but the data shows a smaller increase in success rates following such interactions.
The median days to allowance stands at 1412. This duration represents the typical timeframe for applications that successfully navigate the examination process under this examiner. The relatively long pendency and moderate allowance rate suggest that prosecution in this unit requires careful preparation and sustained effort. These historical cases provide a stable baseline for applicant expectations.
