Tech Center 1700 • Art Units: 1693 1758 1797
This examiner grants 45% of resolved cases
May Leung Chiu serves in Tech Center 1700 and Art Unit 1693. With 29 resolved cases, the examiner has an allowance rate of 44.8%. This figure indicates that fewer than half of the applications are granted, suggesting a rigorous examination process. Practitioners should also consider the median days to allowance of 1292, which reflects the typical time required to reach a successful conclusion in this art unit.
The data shows an interview lift of 24.4%, which is a substantial increase in the likelihood of success following a direct meeting. This 24.4% lift suggests that the examiner is receptive to oral arguments and that interviews are a productive tool for clarifying the claimed invention. Given the 44.8% baseline, the boost provided by an interview can be a critical factor in moving a case toward allowance.
In the context of 29 resolved cases, the 1292 median days to allowance and the 24.4% interview lift provide actionable insights for patent strategy. Applicants in Art Unit 1693 may face a challenging path, but the data clearly supports the use of interviews to improve prosecution results. Tech Center 1700 practitioners should plan for a long duration while leveraging the significant lift observed in this examiner's history.
