Analysis

Xiaoming Liu has resolved 609 cases in Tech Center 2800 and Art Unit 2812. The examiner's allowance rate is 86.5 percent, which serves as a primary indicator of prosecution success. Applicants typically experience a median of 823 days to allowance under this examiner's supervision. This 823-day figure is a metric for planning the timing of patent filings and responses. The 86.5 percent rate provides a baseline for the likelihood of a grant for cases reaching a final resolution.

The interview lift of 10.7 percent provides a measurable change in the probability of allowance for those who engage in examiner interviews. This lift is calculated relative to the 86.5 percent baseline allowance rate. The data suggests that verbal discussion can be a tool for resolving remaining issues in the 609 resolved cases. Practitioners should factor the 823-day median pendency into their decision to use an interview. These metrics offer a consistent view of the prosecution environment in Art Unit 2812.
