Analysis

John Joseph Skoko III handles cases in Art Unit 1612 within Tech Center 1600. With 113 resolved cases, the examiner has an allowance rate of 53.1 percent. This figure suggests a more challenging prosecution environment compared to examiners with higher allowance rates in the same tech center. Practitioners should prepare for rigorous examination given the 53.1 percent allowance rate.

However, the interview lift of 58.2 percent is exceptionally high. This suggests that personal communication is a critical tool for practitioners to improve the odds of allowance significantly above the baseline. The 58.2 percent lift indicates that interviews are highly effective at resolving issues that might otherwise lead to a rejection in Art Unit 1612.

The median days to allowance is 1345, indicating a longer prosecution timeline that may require persistent effort. This duration of 1345 days should be factored into the overall strategy for applications in Tech Center 1600. By analyzing the 113 resolved cases, practitioners can see that while the process is lengthy, interviews offer a strong path to success.
