Analysis

Alex Kok Soon Liew serves in Tech Center 3700 and Art Unit 2624. The examiner has a high volume of experience with 1114 resolved cases. The allowance rate for these cases is 87.6 percent. This metric indicates a high frequency of patent grants for applications reaching a final resolution. The large number of 1114 cases ensures the reliability of these performance statistics.

The median days to allowance is 944. This timeline shows the typical pendency for successful applications under Liew's supervision. The interview lift is 7.2 percent. While positive, this lift is smaller than the 87.6 percent allowance rate, suggesting that many applications proceed to allowance without the need for an interview. However, the 7.2 percent increase still offers a benefit for more complex cases.

For those filing in Art Unit 2624, the 87.6 percent allowance rate and 944 median days to allowance define a predictable environment. The 1114 resolved cases reflect a deep history of examination. Although the 7.2 percent interview lift is modest, it remains a tool for practitioners to consider. The data suggests an efficient prosecution path with a high probability of success.
