Examiner: LEONG, SUSAN DANG

Analysis

Susan Dang Leong examines patent applications within Tech Center 4100 and Art Unit 1700. She has a record of 546 resolved cases, which provides a statistically significant basis for analyzing her prosecution trends. Her overall allowance rate is 63.7 percent, indicating that more than half of the applications assigned to her docket result in a patent grant. This 63.7 percent rate suggests that while she is open to granting patents, she maintains a standard for patentability that requires clear advocacy from practitioners.

One of the most notable aspects of her profile is the interview lift of 39.1 percent. This 39.1 percent lift represents the increase in the likelihood of allowance following an interview, suggesting that personal interaction is an effective tool for applicants. The median days to allowance is 1155, which means the typical successful prosecution lasts over three years. Practitioners should plan for this 1155-day timeline and consider an early interview to potentially expedite the process and improve the 63.7 percent baseline chance of success. The data indicates that direct engagement with the examiner is a primary strategy for navigating Art Unit 1700 under her review.
