This examiner grants 49% of resolved cases

Analysis

Examiner Craigo has an allowance rate of 49.2% across 746 resolved cases in Art Unit 1615. This indicates a challenging environment in Tech Center 1600, where a minority of applications result in a grant. The median days to allowance of 1282 also points to a long and potentially difficult prosecution process. With 746 resolved cases, these statistics provide a robust and sobering outlook for applicants in this biotechnology sector.

The most significant data point is the interview lift of 38.2%. This is an exceptionally high figure, suggesting that interviews are extremely effective at overcoming rejections. For the 746 resolved cases, an interview appears to be the most critical factor in achieving an allowance. Practitioners should prioritize early and frequent communication to navigate the 1282-day median timeline and improve their 49.2% success rate. The 38.2% lift is a clear signal that the examiner is highly responsive to verbal arguments and collaborative problem-solving. Utilizing this tool is essential for any applicant hoping to secure a patent in this rigorous art unit.
