Analysis

Sean James Steinke is an examiner in Tech Center 1700 and Art Unit 1613. The examiner has managed 16 resolved cases. The data shows an allowance rate of 12.5 percent, which indicates that a small minority of applications reach issuance. This rate suggests a very rigorous examination process where the vast majority of cases result in abandonment rather than a grant.

Despite the low base allowance rate, the interview lift is 42.9 percent. This high lift suggests that conducting an interview is a critical strategy, as it significantly increases the probability of an allowance. Practitioners can use this 42.9 percent lift to prioritize direct communication as a primary method for overcoming rejections. This impact is a defining characteristic of the examiner's historical data in Art Unit 1613.

The median time to allowance is 1200 days. This figure represents the typical duration for the prosecution cycle for successful applications. With 16 resolved cases as the basis for these metrics, the profile provides an indication of the timeline and success rates expected. These figures help practitioners manage expectations regarding the duration of the process in Tech Center 1700.
