Tech Center 2600 • Art Units: 2617 2645

This examiner grants 90% of resolved cases

Analysis

William D. Cumming is an examiner in Tech Center 2600 and Art Unit 2617, where he has resolved 1026 cases. He demonstrates an allowance rate of 89.9%, which points to the outlook for patent applications in his docket. The median days to allowance for these cases is 932, providing a benchmark for the expected duration of the prosecution phase. This 932-day timeline is a key consideration for applicants in the 2600 Tech Center.

The interview lift of 5.7% suggests that the 89.9% allowance rate is largely independent of whether an interview is conducted. For the 1026 resolved cases, the 932-day median pendency is a metric for applicants to monitor. Given the baseline success rate, practitioners might focus on the timeline rather than the marginal 5.7% lift provided by interviews. The consistency shown across 1026 cases suggests that the 89.9% allowance rate is a reliable expectation for future filings in Art Unit 2617.
