Analysis

Matthew L. Hamilton is an examiner in Tech Center 3600, assigned to Art Unit 3626. With 524 resolved cases, the examiner has a well-documented history that provides a solid basis for analysis. The allowance rate is 53.4 percent, which indicates that more than half of the applications result in a patent grant. This 53.4 percent rate suggests a moderately challenging environment for applicants in Art Unit 3626.

The median days to allowance is 1506, reflecting a very long prosecution cycle. This 1506-day duration is a significant factor for practitioners to consider when planning their strategy. However, the interview lift percentage is remarkably high at 62.2. This 62.2 percent lift is a critical metric, as it shows that conducting an interview dramatically increases the probability of securing an allowance. In a docket where the baseline allowance rate is 53.4 percent, the 62.2 percent lift suggests that direct engagement with the examiner is a highly effective tactic for overcoming obstacles. For those operating in Tech Center 3600, the combination of a 1506-day median pendency and a massive 62.2 percent interview lift highlights the importance of proactive communication to achieve a successful outcome.
