This examiner grants 46% of resolved cases
Audrey Y Chang is an examiner in Tech Center 3700 and Art Unit 2831. With a high volume of 1275 resolved cases, the examiner has an allowance rate of 46.5%. This 46.5% rate suggests a balanced but slightly challenging environment where less than half of the applications reach allowance. The 1275 resolved cases provide a very stable statistical basis for this trend.
The interview lift is 20.4%, indicating that direct communication with the examiner is a productive strategy. This 20.4% lift can be used to improve the probability of success and resolve rejections. The median days to allowance is 1250, which is the typical timeframe for reaching a successful outcome. Practitioners should plan for a 1250-day process and consider the 20.4% lift as a key tactical tool. Given the 46.5% allowance rate, the 1250-day median represents the time investment required for a successful prosecution. The 1275 resolved cases show that the examiner maintains a consistent approach to patent examination.
