Analysis

Roy B. Rhee is an examiner in Tech Center 3600, specifically Art Unit 3661, with 162 resolved cases. His allowance rate of 69.8% indicates a generally favorable environment, with a majority of his cases resulting in a grant. This rate provides a solid baseline for applicants to gauge their prospects for success when their applications are assigned to his docket for examination.

The median days to allowance is 1137, which reflects a prosecution timeline that typically extends for a significant period. The data also reveals an interview lift of 23.2%. This figure shows that conducting an interview can provide a significant boost to the chances of allowance, increasing the probability beyond the 69.8% baseline and helping to resolve any outstanding issues more effectively through direct communication.

With 162 resolved cases, the 23.2% interview lift is a statistically grounded reason to consider an interview. The 1137-day median duration offers a clear expectation for pendency. Practitioners should view the combination of a 69.8% allowance rate and a strong interview lift as an opportunity to secure patent rights effectively within Art Unit 3661 by engaging proactively with the examiner.
