Analysis

Jason R Bellinger examines applications in Tech Center 4100 and Art Unit 1759, with a large volume of 1245 resolved cases. The allowance rate is 70.0 percent, which is quite high and suggests a receptive approach to patent prosecution. This 70.0 percent rate, established over 1245 cases, provides a strong statistical basis for expecting a favorable outcome.

The interview lift of 18.7 percent is a significant positive indicator. It suggests that engaging in an interview with the examiner increases the likelihood of allowance by a substantial margin over the 70.0 percent baseline. For practitioners, the 18.7 percent lift highlights the value of direct communication in Art Unit 1759.

The median days to allowance is 1070. This duration is a key factor for planning, as it defines the typical timeline for reaching a grant. Given the 1245 resolved cases, the 70.0 percent allowance rate and 1070-day median are well-supported. The 18.7 percent interview lift offers a clear strategy for potentially improving the odds of success within that 1070-day period.
