Analysis

Krishna Jayanthi Palaniswamy is assigned to Art Unit 1721 in Tech Center 4100. The examiner has resolved 25 cases, which is a smaller sample size compared to some peers, yet it yields an allowance rate of 76.0 percent. This rate indicates a strong likelihood of success for applications reaching a final resolution. The median days to allowance for these cases is 1167, establishing a timeline for the examination process in this specific art unit. Practitioners should note this duration when advising clients on the expected life cycle of their patent applications. The 25 resolved cases provide the foundation for these metrics.

A notable feature of this examiner's profile is the interview lift of 30.7 percent. This is a significant increase over the 76.0 percent allowance rate, suggesting that personal interaction is highly effective in Art Unit 1721. With only 25 resolved cases, each outcome has a substantial impact on the statistics, but the 30.7 percent lift is a compelling reason to request an interview early in the process. The 1167-day median pendency might be mitigated or more effectively managed by leveraging this high lift. This data provides a clear tactical advantage for those prosecuting cases before this examiner, offering a roadmap for successful patent acquisition.
