This examiner grants 38% of resolved cases

Analysis

Aurora M. Fontainhas examines cases in Tech Center 1600 and Art Unit 1649, with 496 resolved cases in her portfolio. The allowance rate of 37.9 percent indicates a rigorous standard for patentability, where applicants must be prepared for significant pushback. Applicants should also be prepared for a median days to allowance of 1190, reflecting a thorough and potentially lengthy examination process. This duration suggests that reaching an agreement on claim scope may take a considerable amount of time.

The data reveals a significant interview lift of 49.2 percent, which is one of the most effective tools for improving the 37.9 percent allowance rate. This high lift suggests that direct communication can clarify technical issues and lead to more favorable outcomes than written responses alone. With 496 resolved cases, the impact of interviews is a well-documented strategy for navigating this examiner's requirements. Practitioners in Art Unit 1649 should consider scheduling an interview as a standard part of their prosecution plan to mitigate the 1190-day median wait.
