Examiner: GLESSNER, BRIAN E

Analysis

Brian E. Glessner has resolved 171 cases in Art Unit 3633 within Tech Center 3600. The allowance rate is 35.7%, which suggests a rigorous examination process where many applications do not survive to issuance. This rate indicates that the examiner maintains a high threshold for patentability, requiring practitioners to be very persuasive in their arguments. The median days to allowance is 1142, showing that reaching a grant takes over three years on average for the 171 cases resolved.

A key strategy for this examiner is the use of interviews, as shown by the 26.3% interview lift. This significant lift suggests that direct communication can substantially improve the 35.7% baseline allowance rate by resolving misunderstandings or clarifying claim scope. Practitioners should consider early interviews to navigate the challenging environment and potentially shorten the 1142-day timeline. The data indicates that while the initial path is difficult, personal engagement is a highly effective way to move toward a grant.
