This examiner grants 0% of resolved cases

Analysis

Vivian Dang Ho operates within Tech Center 2400 and Art Unit 2431. The examiner has a very small sample size of 1 resolved case. This single resolution resulted in an allowance rate of 0.0%, indicating that the case did not reach a grant. The median days to allowance for this examiner is recorded as 764, which provides a baseline for the time spent on the resolution process.

The data shows an interview lift of 0.0%. This suggests that for the 1 resolved case, an interview did not lead to a change in the outcome. Practitioners should note that with only 1 resolved case, these percentages are highly sensitive and may not reflect long-term trends. The 764 days to allowance is the only temporal metric available for evaluating the examiner's docket speed.

Given the limited history in Art Unit 2431, applicants should approach prosecution with a focus on clear initial filings. The 0.0% allowance rate and 0.0% interview lift are based on a single data point, making it difficult to predict future behavior. However, the 764-day duration suggests a standard processing time for the resolved matter within Tech Center 2400.
