Analysis

Alexander Khong is an examiner in Tech Center 2600 and Art Unit 2155, where he has handled 656 resolved cases. He maintains a high allowance rate of 84.1 percent. Prosecution is relatively fast, with a median days to allowance of 900, indicating an efficient process for the 84.1 percent of cases that result in a grant.

The interview lift is 27.8 percent, which is a very strong indicator of the value of personal engagement. This lift suggests that Khong is highly receptive to arguments made during interviews. For practitioners, this data points to a clear strategy: while the 84.1 percent baseline success rate is already high, an interview can further increase the odds of a favorable outcome and potentially resolve issues more quickly.

Strategy for this examiner should focus on the 900 median days to allowance as a baseline for planning. The 84.1 percent allowance rate is very encouraging, and the 27.8 percent interview lift is a powerful tool. Practitioners should use interviews to resolve any technical disagreements, as this approach statistically improves the likelihood of a grant and maintains prosecution efficiency.
