Analysis

Christina Renee Daulton is a patent examiner assigned to Tech Center 1700 and Art Unit 1725. The examiner's record includes 23 resolved cases, which provide the data for the metrics in this profile. Among these 23 cases, the allowance rate is 34.8 percent. This 34.8 percent rate is a primary figure for practitioners to consider when their applications are under review. The data offers a view of the examiner's historical outcomes during the prosecution process in Tech Center 1700.

The median days to allowance for applications that result in a grant is 1391. This 1391-day period represents the middle value of the time from the initial filing to the issuance of a patent. Practitioners can use the 1391-day figure to estimate the duration of the examination cycle. The 1391-day median is a relevant metric for managing the expectations of stakeholders regarding the timing of patent protection. This timeframe is a characteristic of the examiner's work within Art Unit 1725.

The profile also includes an interview lift of 3.0 percent. This 3.0 percent lift measures the difference in allowance rates between cases that include an interview and those that do not.
