Analysis

Sherman L Lin works in Tech Center 2400 and Art Unit 2447, with 260 resolved cases. The examiner's allowance rate is 29.2 percent, which suggests a rigorous examination process. This 29.2 percent rate indicates the frequency of grants among the 260 cases resolved, requiring applicants to be well-prepared for prosecution. The 29.2 percent figure is a key metric for assessing difficulty.

The interview lift for this examiner is 37.1 percent. Despite the 29.2 percent base allowance rate, the 37.1 percent lift shows that interviews are an effective way to improve the chances of success. This increase suggests that direct communication can help bridge the gap between a rejection and an allowance in Art Unit 2447. Practitioners should factor the 37.1 percent lift into their strategy.

The median days to allowance is 1844 days. This 1844-day figure reflects the prosecution process for the cases that eventually reach allowance. The combination of a 29.2 percent allowance rate and an 1844-day median indicates the path to securing a patent under this examiner's review.
