Analysis

Kenneth N. Vanderpuye has resolved 67 cases in Art Unit 2613. The allowance rate is 23.9 percent, and the median days to allowance is 1230. These figures indicate a challenging environment in Tech Center 2600. The 67 cases provide a clear view of the examiner's historical patterns and rigorous standards.

The interview lift is 0.0 percent. This 0.0 percent lift suggests that interviews have not historically increased the likelihood of an allowance. Applicants facing the 23.9 percent allowance rate and 1230-day timeline should carefully evaluate their strategy, as the 0.0 percent lift indicates that interviews may not be effective. The 1230-day median pendency and 23.9 percent allowance rate require a focused approach to prosecution. Given the 67 cases of experience, the 0.0 percent lift is a strong indicator that alternative methods may be needed to secure an allowance in Art Unit 2613.
