This examiner grants 77% of resolved cases

Analysis

Donald Joseph Wallace has overseen 455 resolved cases in Art Unit 3662, which is part of Tech Center 3600. The examiner's allowance rate of 76.9 percent suggests a relatively favorable path for applicants seeking patent protection. This 76.9 percent rate indicates that the examiner is generally receptive to arguments and amendments that clearly define the invention over the prior art.

The median days to allowance is 1054, providing a clear benchmark for the expected duration of the prosecution process. With an interview lift of 16.0 percent, direct engagement with the examiner provides a meaningful increase in the probability of allowance. This 16.0 percent lift complements the already solid baseline grant rate, making interviews a useful tool for resolving any outstanding rejections.

Practitioners should use the 1054 day median to manage their prosecution timelines and consider an interview if they face an impasse. While the 76.9 percent allowance rate is strong, the 16.0 percent lift shows that verbal communication can still provide a significant advantage. Overall, the data suggests a predictable and generally successful experience for applicants in Art Unit 3662.
