Analysis

Duc Chi Ho serves in Tech Center 2600 and Art Unit 2419. He has a large dataset of 1219 resolved cases and a very high allowance rate of 92.8 percent. The median days to allowance is 865, reflecting an efficient and successful prosecution environment. With over twelve hundred cases resolved, the data demonstrates a stable and predictable landscape where more than nine out of ten applications reach a grant in less than two and a half years.

The interview lift is 7.7 percent, which is a modest but positive increase. With an allowance rate of 92.8 percent, the examiner appears very receptive to granting patents through standard written prosecution. The 7.7 percent lift is a useful tool for resolving any specific technical points that may arise compared to the 92.8 percent baseline. The high volume of 1219 cases confirms that these metrics are a reliable indicator of the examiner's consistent performance. Practitioners can use the 865-day median pendency to plan their prosecution timelines with a high degree of confidence. These statistics show a very favorable environment for those seeking patent protection under this examiner's review in Art Unit 2419.
