Tech Center 2600 • Art Units: 2613 2634 2636

This examiner grants 78% of resolved cases

Analysis

Examiner Cors has handled 1025 resolved cases in Art Unit 2613, maintaining an allowance rate of 77.7%. This rate indicates a generally receptive approach to patentability within Tech Center 2600. The median days to allowance of 1003 suggests that applicants can expect a resolution after a significant period of prosecution time. The large volume of 1025 resolved cases ensures that these performance metrics are statistically significant and reliable for planning purposes.

While the interview lift of 5.4% is positive, it is more modest than other examiners in similar fields. This suggests that while interviews are helpful, the 1025 resolved cases were often decided based on written arguments or standard amendments. Practitioners should focus on clear written records while utilizing interviews as a secondary tool to bridge minor gaps in understanding. The 77.7% allowance rate remains a strong baseline for success, and the 1003-day median pendency provides a clear expectation for the duration of the process. Strategic focus should remain on technical clarity to maintain the high probability of grant.
