She maintains an allowance rate of 90.3%, which is a very high mark that suggests a streamlined path to patent issuance for most applicants.

The median days to allowance for this examiner is 808, reflecting a relatively efficient prosecution timeline. Additionally, the data shows an interview lift of 2.0%, which indicates a slight increase in the probability of success following an interview. Given the high base allowance rate, this modest lift suggests that written amendments and arguments are often sufficient to reach a grant. The 808-day median pendency is an attractive feature for applicants seeking a quick resolution in Art Unit 2812.

For practitioners, the strategy with this examiner should focus on high-quality written submissions, though interviews remain a viable option. The 2.0% lift suggests that the 722 resolved cases were largely decided on the merits of the written record.
