Analysis

Ahmad Hussam Shalaby is an examiner in Tech Center 4100 and Art Unit 2187. His profile is currently based on 2 resolved cases. Neither of these cases resulted in an allowance, leading to a 0.0 percent allowance rate. While this is a challenging start, the small sample size of 2 cases means that this rate may change as more applications reach a resolution in his docket. The 2 resolved cases provide the initial data.

The interview lift is recorded at 0.0 percent. This figure reflects the fact that for the 2 resolved cases on record, interviews did not result in an allowance. Since the baseline is already 0.0 percent, there is no room for a positive lift in this specific metric until a case is granted. Practitioners should monitor future data to see how this 0.0 percent lift evolves as the examiner's volume grows over time. The 0.0 percent allowance rate is the current benchmark.

The median days to allowance is 1521. This timeline represents the duration for cases in the record, although none have yet reached a grant. A pendency of 1521 days suggests a protracted path for applicants. As more cases are added to the history, this 1521 day figure will provide a more comprehensive view of the examination timeline in Art Unit 2187. The 2 resolved cases offer a preliminary look at the process.
