This examiner grants 87% of resolved cases

Analysis

Ryan D. Walsh is a high-volume examiner in Art Unit 2852 of Tech Center 2800, with 1049 resolved cases. The allowance rate of 86.9 percent is notably high, indicating a streamlined path to grant for most applications. This 86.9 percent rate suggests that the examiner is highly efficient at identifying allowable subject matter and moving cases toward issuance in a consistent and predictable manner.

Efficiency is further evidenced by a median days to allowance of 819. This 819 day timeline allows applicants to expect a resolution in well under three years, which is favorable for maintaining business momentum. Although the interview lift is 5.6 percent, the high overall allowance rate implies that written prosecution is often sufficient to reach a positive outcome without the need for verbal intervention.

The 5.6 percent lift provides a small benefit, but the primary driver of success is the 86.9 percent baseline allowance rate. Practitioners should focus on clear and concise written responses to maintain the 819 day efficiency. The large volume of 1049 cases provides a high degree of confidence in these metrics, making this a very favorable docket for patent applicants.
