Tech Center 4100 • Art Units: 2491 4100
This examiner grants 77% of resolved cases
D'Arcy Winston Straub serves in Tech Center 4100 and Art Unit 2491. He has handled 232 resolved cases, which provides a reliable statistical basis for evaluating his performance. His allowance rate of 77.2 percent is quite high, suggesting that he is often able to find a path to grant for the applications he examines. This 77.2 percent rate is a positive sign for applicants seeking patent protection in his technical area.
The interview lift for Straub is 19.6 percent. This indicates that while he is already inclined toward allowance, an interview provides a significant additional advantage. Direct discussion can help refine claims and address any remaining examiner concerns more quickly than iterative written office action responses. Practitioners should consider an interview as a standard part of their strategy to capitalize on this 19.6 percent lift.
The median time to allowance for Straub is 1086 days. This is a relatively fast pace for patent prosecution, coming in under the typical multi-year mark. The combination of the 77.2 percent allowance rate and the 1086-day median pendency suggests an efficient and applicant-friendly examination process. Those with cases in Art Unit 2491 can expect a relatively smooth and timely path to a final disposition.
