Analysis

Maureen Wallenhorst is a high-volume examiner in Art Unit 1672, with 1414 resolved cases. The allowance rate of 78.9 percent indicates a favorable environment for patent grants within Tech Center 1700. This 78.9 percent rate suggests that the examiner is consistent and fair, allowing the vast majority of applications that properly define the invention over the prior art.

Efficiency is a key metric for this examiner, as shown by a median days to allowance of 791. This 791 day timeline is quite fast, especially considering the large volume of 1414 cases handled. While the interview lift is 5.8 percent, the strong baseline allowance rate suggests that the examiner is generally receptive to well-supported written arguments and that interviews may only be needed in exceptional circumstances.

Practitioners should aim for high-quality written submissions to take advantage of the 791 day efficiency. The 5.8 percent lift provides a small benefit, but the 78.9 percent allowance rate is the primary indicator of success. The large sample size of 1414 cases provides a high degree of confidence in these metrics, making this a predictable and efficient docket for patent applicants.
