Analysis

Frances F. Hamilton is an examiner in Tech Center 3700, working in Art Unit 3743. With 665 resolved cases, the examiner has a well-established record for analysis. The allowance rate is 53.8 percent, which indicates that more than half of the applications result in a patent grant. This 53.8 percent rate suggests a moderately challenging prosecution environment where applicants must be prepared for substantive rejections in Art Unit 3743.

The median days to allowance is 1410, reflecting a long prosecution cycle. This 1410-day duration is an important factor for practitioners to consider when managing client expectations. However, the interview lift percentage is 38.6, which is quite high. This 38.6 percent lift indicates that interviews are very effective at increasing the probability of an allowance. Given the 53.8 percent baseline allowance rate, the 38.6 percent lift suggests that direct engagement with the examiner is a highly effective strategy for overcoming hurdles. For those operating in Tech Center 3700, the combination of a 1410-day median pendency and a 38.6 percent interview lift highlights the value of proactive communication to improve the odds of a successful outcome.
