Analysis

William C. Vaughn Jr. is an examiner in Art Unit 2143 of Tech Center 2400, with 54 resolved cases. The allowance rate is low at 33.3%, and the median days to allowance is 1249. This indicates a challenging and somewhat slow prosecution process for the 54 resolved cases. Applicants should be prepared for a high rate of rejection and a timeline that may involve multiple rounds of examination before a final resolution is reached.

However, the interview lift of 51.2% is very high, suggesting that interviews are a critical tool for overcoming the 33.3% baseline. This 51.2% lift indicates that direct communication can dramatically improve the odds of success and help resolve technical disagreements. For the 54 resolved cases, the data shows that an interview is a highly recommended strategy. The 1249-day median pendency should be factored into the prosecution plan, and practitioners should use interviews early to move toward a grant more effectively. Given the substantial lift, an interview could be the most important step in achieving a favorable outcome with this examiner.
