This examiner grants 79% of resolved cases

Analysis

Michael R. Vaughan works in Art Unit 2431 of Tech Center 2400, with 818 resolved cases. The allowance rate is 78.6%, and the median days to allowance is 1096. This indicates a favorable prosecution environment with a moderate timeline for the 818 resolved cases. Applicants have a high probability of success, and the examiner appears to follow a consistent and predictable path toward granting applications.

The interview lift of 30.8% is quite high, suggesting that interviews are very effective at improving the 78.6% baseline. This 30.8% lift indicates that direct communication can be a key factor in resolving technical issues and overcoming rejections. With 818 resolved cases, the data strongly supports the use of interviews to secure a grant. The 1096-day median pendency is typical for this tech center, and practitioners can use interviews to potentially streamline the process and ensure a successful outcome. A strategy that incorporates early interviews is likely to be highly effective in Art Unit 2431, given the examiner's strong responsiveness to verbal advocacy.
