Analysis

Bo Ouyang is assigned to Tech Center 3700 and Art Unit 3739, where he has reached a disposition on 409 resolved cases. The allowance rate of 60.6 percent suggests the level of difficulty for applicants in this unit. This rate implies that while a majority of applications succeed, a portion do not result in a patent grant, necessitating a prepared prosecution strategy. The 409 resolved cases reflect the examination style within this specific art unit.

The interview lift of 8.8 percent indicates a measurable benefit to holding an interview with the examiner. Furthermore, the median days to allowance is 1462, pointing toward the prosecution cycle for those cases that are eventually allowed. With 409 resolved cases, these statistics provide a picture of the procedural expectations and timelines. Practitioners should be prepared for the 1462 median days to allowance and may find that interviews provide a helpful push to overcome rejections.
