Analysis

Suberr L Chi works in Tech Center 2800 and Art Unit 2800, with 657 resolved cases. The examiner maintains an allowance rate of 84.5%, suggesting a positive outlook for most applications. The interview lift is 2.8%, which indicates that interviews have a minimal impact on the 84.5% baseline allowance rate. This suggests that written arguments are likely the primary driver of success in this examiner's queue.

The median days to allowance is 1018, representing the typical duration for successful cases among the 657 resolved. This 1018-day metric is a key planning factor for practitioners in Art Unit 2800. While the 84.5% allowance rate is encouraging, the 2.8% interview lift suggests that verbal advocacy offers only a slight advantage. Applicants should expect a prosecution cycle of approximately 1018 days. These metrics provide a stable foundation for developing a strategy in Tech Center 2800.
