This examiner grants 32% of resolved cases

Analysis

Cho Yiu Kwong is an examiner in Tech Center 3600, working within Art Unit 3693. He has managed 331 resolved cases, providing a robust data set for analysis. The allowance rate is 32.3 percent, which is relatively low and indicates a challenging prosecution environment. Applicants should be prepared for a rigorous examination and a higher probability of rejection. The 32.3 percent rate suggests that the examiner maintains a strict standard for patentability.

The interview lift is 4.3 percent, which is quite low. This indicates that interviews do not significantly change the probability of an allowance compared to written prosecution alone. The median time to allowance is 1489 days. This is a very long duration, so practitioners should prepare their clients for an extended prosecution cycle. Given the 32.3 percent allowance rate and the 1489 days of median pendency, the most effective strategy is likely to focus on building a very strong written record. The 4.3 percent lift suggests that while interviews are possible, they may not be the primary driver of success. Practitioners should factor these metrics into their overall strategy for managing client expectations and resources.
