Analysis

Eric Andrew Gates is a prolific examiner in Tech Center 3700 and Art Unit 3641, with 1112 resolved cases. The examiner maintains a strong allowance rate of 78.8%, suggesting a relatively accessible path to patent issuance for most applications. This favorable environment indicates that the majority of applicants are successful in securing patent rights.

The data shows an interview lift of 14.5%. This positive lift suggests that interviews are an effective strategy for further increasing the probability of allowance, even when the baseline rate is already high. Oral advocacy can be a productive way to resolve any remaining issues and move the application toward a grant more efficiently.

The median days to allowance is 1008. This timeframe indicates a standard prosecution pace for the tech center, providing applicants with a predictable expectation for the duration of the patent acquisition process. The combination of a high allowance rate and a positive interview lift makes this a relatively efficient prosecution environment.
