Analysis

Mark A. Shabman is an examiner in Art Unit 2855 of Tech Center 2800. The examiner has managed 1060 resolved cases, providing a very large data set for evaluating prosecution behavior. The allowance rate of 84.2 percent indicates the proportion of these cases that resulted in a patent grant. This figure provides a reliable baseline for the likelihood of securing an allowance. Practitioners can use this rate to evaluate the examiner's general receptiveness to patentable subject matter.

The interview lift of 13.4 percent shows an increase in the allowance rate when an interview is conducted. This metric suggests that verbal communication is an effective tool for resolving issues and advancing prosecution toward a grant. The median days to allowance is 941, which serves as a temporal benchmark for the duration of the prosecution cycle. This timeframe is useful for setting expectations regarding the total time from filing to a successful outcome. The 1060 resolved cases ensure that these performance metrics are statistically significant.
