This examiner grants 38% of resolved cases

Analysis

Matthew Curran Metcalf, in Tech Center 1600 and Art Unit 1622, has 8 resolved cases. The allowance rate is 37.5 percent, but the interview lift is a very high 71.4 percent. This 71.4 percent lift is extremely significant compared to the 37.5 percent baseline. The 37.5 percent allowance rate is low, but the 71.4 percent lift suggests that interviews are the most effective way to get a case allowed.

The median time to allowance is 1300 days. While the 37.5 percent allowance rate is challenging, the 71.4 percent interview lift is a powerful tool for applicants. Counsel should be prepared for a 1300 day timeline and should always request an interview. With only 8 resolved cases, the data is limited but clear on the value of interviews. The 1300 day pendency and 71.4 percent lift are the defining characteristics of prosecution with this examiner. Utilizing the 71.4 percent lift is essential for success.
