Analysis

David Yi serves in Art Unit 1634 of Tech Center 2400. He has 258 resolved cases with an allowance rate of 69.0 percent. The median time to reach an allowance is 1452 days, which is a lengthy duration for patent prosecution. The 69.0 percent allowance rate indicates a generally positive outlook for applicants who persist through the process.

The data shows an interview lift of 64.5 percent. This is a very high lift, suggesting that interviews are a critical tool for success with this examiner. While the overall allowance rate is 69.0 percent, the significant lift and long pendency of 1452 days imply that interviews can help navigate complex issues and potentially shorten the path to a grant. Practitioners should prioritize early interviews to address examiner concerns. The 64.5 percent lift is a strong indicator that the examiner is highly responsive to verbal discussion. With 258 resolved cases, the data highlights the importance of direct engagement. This strategy is essential for managing the 1452-day median timeline.
