This examiner grants 77% of resolved cases

Analysis

David P. Hatch has managed 122 resolved cases within Art Unit 3668 of Tech Center 3600. His allowance rate of 77.0% indicates a high frequency of granted patents relative to the total number of resolutions. This figure provides a baseline for expectations when filing in his specific area of examination. The 77.0% allowance rate suggests that the majority of applicants who persist in prosecution will eventually secure a patent grant.

The 11.8% interview lift suggests that direct communication with the examiner is a productive tactic for advancing prosecution. Engaging in an interview appears to correlate with a higher probability of allowance compared to cases where no interview occurs. This strategy may be particularly useful given the median days to allowance of 989. Practitioners should consider the interview as a tool to potentially resolve complex rejections more efficiently.

The 989 median days to allowance represents the middle point of the timeline for successful applications. Practitioners should prepare for a process that spans this specific duration from filing to grant. This timeline, combined with the 122 resolved cases, defines the typical experience for applicants in this docket. Understanding these metrics allows for more accurate budgeting and timeline management during the patent acquisition process.
