Analysis

Examiner SHUM, KENT N is part of Tech Center 3700 and Art Unit 3722. The examiner has 121 resolved cases on record. The allowance rate for these cases is 37.2 percent, which represents the proportion of applications that result in a patent grant. The median time to reach an allowance is 1265 days. This 1265-day timeline is a factor for applicants to consider when managing their prosecution schedules.

The interview lift is 49.6 percent, which is greater than the 37.2 percent overall allowance rate. This 49.6 percent lift indicates that conducting an interview is associated with an increase in the likelihood of a patent being granted. Given the 37.2 percent allowance rate and the 1265-day median, the 49.6 percent lift suggests that direct communication is a strategy for overcoming the challenges of prosecution. With 121 resolved cases, these figures provide a statistical picture of the environment in Art Unit 3722 within Tech Center 3700.
