Analysis

David S. Perlman is a patent examiner in Art Unit 2624 within Tech Center 2600. He has a significant history of 550 resolved cases, providing a reliable data set for understanding his prosecution tendencies. The allowance rate of 80.9% is quite high, suggesting that applicants have a strong likelihood of obtaining a patent when their cases are assigned to this examiner. This high rate indicates a generally favorable environment for patent grants in this art unit.

The interview lift for this examiner is 12.6%. This positive lift indicates that conducting an interview can further improve the chances of an allowance, even beyond the already high baseline. For practitioners, this means that personal engagement is an effective tool for resolving rejections and clarifying technical issues. The 12.6% lift suggests that the examiner is receptive to verbal arguments and collaborative problem-solving, making interviews a recommended strategy for cases that do not receive an immediate allowance. Direct interaction can help expedite the process.

The median days to allowance is 928, which offers a predictable timeline for the prosecution process. This duration is relatively efficient, allowing applicants to move from filing to grant in a reasonable amount of time. The combination of an 80.9% allowance rate and a 12.6% interview lift suggests a prosecution path that is both successful and responsive to direct communication. Applicants in Tech Center 2600 can use these metrics to refine their strategies and optimize their chances of a grant within the 928 day median pendency.
