This examiner grants 0% of resolved cases

Analysis

Catherine Joh is an examiner in Tech Center 3700 and Art Unit 3723. Her current profile is based on 1 resolved case, which did not result in a grant, leading to an allowance rate of 0.0 percent. Because this rate is derived from a single case, it may not represent the examiner's overall tendencies as her caseload increases beyond this initial resolution.

The median time to allowance for the examiner is 1011 days. The data also shows an interview lift of 0.0 percent, though this figure is also based on the single resolved case. Practitioners should be aware of the 1011-day timeline but should exercise caution when interpreting these metrics due to the sample size of 1 case. As more cases are resolved in Art Unit 3723, the data will provide a further view of the prosecution environment.
