Analysis

Matthew M. Barker is an examiner in Art Unit 3646 of Tech Center 3600. He has handled a volume of 789 resolved cases, resulting in an allowance rate of 72.5 percent. This volume of cases provides a stable statistical basis for evaluating his performance. The median days to allowance is 1161, indicating a prosecution cycle that typically lasts a significant duration. This 1161-day cycle requires applicants to maintain a long-term perspective on their strategy.

The interview lift is 14.9 percent, which offers a clear benefit for applicants who choose to interview. Given the 72.5 percent allowance rate, practitioners should weigh the 14.9 percent lift against the 1161-day median pendency when deciding on prosecution tactics. The 789 resolved cases suggest that these metrics are likely to persist in Art Unit 3646. The 14.9 percent lift can be a factor in moving a case toward allowance during the later stages of prosecution.
