Michael J. Stahl is an examiner in Tech Center 2800 and Art Unit 2828. He has overseen 1282 resolved cases. The examiner demonstrates an allowance rate of 90.1 percent, which indicates that the vast majority of applications result in a patent grant. This high frequency of issuance provides a predictable path for applicants navigating the prosecution process in this unit.
The median time to allowance is 727 days. This figure represents the typical duration for applications to move from filing to a successful grant. Practitioners can use this 727 day median to estimate the timeline for their cases. The efficiency shown in these 1282 resolved cases is a notable feature of the examiner's historical performance.
Direct engagement with the examiner yields an interview lift of 7.5 percent. This positive lift suggests that interviews are a useful tool for further increasing the chances of an allowance. Even with a base allowance rate of 90.1 percent, the 7.5 percent lift indicates that verbal communication remains a beneficial strategy. These combined metrics offer a comprehensive view of the examination environment in Art Unit 2828.
