Analysis

Brian Keith Palmarchuk serves in Art Unit 3669 of Tech Center 3600. The examiner has 27 resolved cases, with an allowance rate of 66.7 percent. This rate indicates that two out of every three cases reaching a resolution are granted. The median days to allowance is 845, which is a relatively efficient timeline for this tech center. While the sample size of 27 cases is smaller than some others, it provides a clear initial picture of the examiner's tendencies and the speed of prosecution in Art Unit 3669. These 27 resolved cases form the basis for the current statistical profile.

The interview lift is 15.0 percent, showing that direct communication with the examiner can further improve the 66.7 percent allowance rate. This lift suggests that interviews are a productive way to address examiner concerns and clarify the claimed invention. The 845-day median pendency is an important metric for applicants who prioritize a faster path to patent issuance. By combining the 66.7 percent allowance rate with the 15.0 percent interview lift, practitioners can develop a targeted strategy for their 27 resolved cases and future filings. This data offers a useful guide for navigating Art Unit 3669 and managing the expectations of patent applicants.
