Tech Center 1700 • Art Units: 1777 1779 1794
This examiner grants 58% of resolved cases
Peter Keyworth, working in Tech Center 1700 and Art Unit 1777, has resolved 794 cases with an allowance rate of 58.3 percent. The prosecution timeline is relatively long, with a median days to allowance of 1285. These figures suggest that while grants are achievable, the process requires persistence and a significant time investment to navigate the 58.3 percent baseline.
The most striking metric is the interview lift of 23.9 percent. This high lift indicates that interviews are exceptionally effective at moving cases toward allowance. For practitioners facing rejections, the data strongly supports the use of examiner interviews as a primary tool to bridge the gap between the examiner's position and the applicant's claims, significantly improving the odds over the 58.3 percent allowance rate.
Given the 1285 median days to allowance, applicants should be prepared for a multi-year prosecution cycle. However, the 23.9 percent interview lift provides a clear path to potentially accelerating this process. Strategy should prioritize early and frequent engagement with Keyworth to capitalize on his receptiveness to verbal arguments and to overcome the moderate baseline allowance rate.
