This examiner grants 78% of resolved cases
Michael A. Riegelman is an experienced examiner in Tech Center 3700 and Art Unit 3654, with 974 resolved cases. His allowance rate of 78.1 percent is high, indicating a favorable environment for patent applicants. This 78.1 percent rate suggests that the examiner frequently finds ways to move cases toward a grant during the prosecution cycle.
The median days to allowance for his docket is 944. This 944 day timeline provides a realistic expectation for the duration of the patenting process. With 974 resolved cases, the data reflects a consistent ability to reach resolutions within this 944 day window while maintaining high allowance levels.
Practitioners should also note the interview lift of 14.8 percent.

Engaging in a dialogue can help clarify technical nuances and potentially improve the chances of success beyond the 78.1 percent baseline during the 944 day prosecution period.
