Examiner: ROGERS, JAMES WILLIAM

Tech Center 1600 • Art Units: 1618

This examiner grants 46% of resolved cases

Analysis

James William Rogers has a significant history in Art Unit 1618, with 904 resolved cases in Tech Center 1600. His allowance rate pct is 46.2, which indicates a more rigorous examination environment where less than half of applications are granted. The median days to allowance is 1407, reflecting a long and potentially difficult path to a patent grant. These 904 resolved cases highlight a challenging landscape for applicants.

Despite the lower allowance rate, the interview lift pct of 22.3 shows that interviews can provide a meaningful boost to an application's chances. While the 46.2 percent baseline is challenging, practitioners can use interviews to clarify issues and potentially improve outcomes. The 22.3 percent lift is a key tactical consideration when navigating the 1407-day median timeline. Proactive communication may be essential to overcome the higher rejection rates seen in this art unit.
