Analysis

Shun K Lee operates in Tech Center 2800 and Art Unit 2884. The examiner has 717 resolved cases with an allowance rate of 42.1 percent. This rate is below a majority, suggesting a challenging prosecution environment. However, the interview lift of 16.1 percent indicates that interviews are a helpful tool for increasing the odds of allowance.

The median days to allowance is 1295. This is a significant duration for the 717 resolved cases. Practitioners should be prepared for a longer timeline when facing the 42.1 percent allowance rate. The 16.1 percent interview lift offers a strategic path to improve these odds.

In Art Unit 2884, the 1295 median days to allowance is a key metric for planning. The allowance rate across resolved cases shows a rigorous standard of examination. The interview lift suggests that engaging the examiner directly can help navigate the complexities of the median process.
