Analysis

Timothy D. Collins examines applications in Tech Center 3600 and Art Unit 3642, with 121 resolved cases on record. The allowance rate of 51.2% indicates a competitive environment for applicants such as BITMAIN TECHNOLOGIES INC. and Inca Products Acquisition Corp. The median days to allowance of 1123 suggests that the prosecution process is steady, providing a clear benchmark for firms like AMPACC Law Group, PLLC.

The data reflects an interview lift of 26.2%, which provides a significant boost to the 51.2% baseline allowance rate. This suggests that direct communication is an effective strategy for applicants seeking to overcome initial rejections. With 121 resolved cases, the 1123-day median pendency is a consistent factor in prosecution strategy, and the 26.2% interview lift indicates that the examiner is open to clarifying technical points through verbal discussion.

Practitioners should consider this metric when deciding whether to file a written response or request a formal interview to move their applications toward a final disposition. The combination of a 51.2% allowance rate and a strong interview lift suggests that while the examiner is thorough, they are also receptive to resolving issues through direct engagement. This approach can be particularly beneficial in navigating the 1123-day median timeline.
