Analysis

Helena Kosanovic has 698 resolved cases in Tech Center 3700 and Art Unit 3743. Her allowance rate is 45.0%, which is higher than the interview lift of 14.6%. The median days to allowance is 1418, indicating the process for those applications that do eventually reach a grant. With 698 resolved cases, the data suggests a pattern of examination that requires persistence from the applicant. This volume of cases provides a view of her prosecution tendencies.

An interview lift of 14.6% suggests that while interviews are beneficial, they offer a smaller increase in the likelihood of grant compared to the 45.0% baseline. Practitioners should prepare for a prosecution lasting around 1418 days. The 45.0% allowance rate means that more than half of the cases do not result in a patent. By analyzing the 698 resolved cases, one can see that the 14.6% lift is a helpful path. The 1418-day median pendency should be factored into the overall patent strategy.
