This examiner grants 52% of resolved cases

Analysis

Latoya M. Louis serves in Art Unit 3771 of Tech Center 3700. With 676 resolved cases, the examiner has an allowance rate of 52.2 percent. This rate suggests a balanced prosecution environment where approximately half of the resolved cases result in an allowance. Practitioners can use the 52.2 percent figure to set realistic expectations for clients regarding the competitive nature of securing a patent in this unit.

The interview lift is 40.5 percent, which is a significant factor for practitioners to consider. This high lift indicates that an interview greatly increases the probability of an allowance compared to cases where no interview is conducted. The 40.5 percent lift suggests that engaging the examiner directly is a highly effective tactic for clarifying the scope of the invention and overcoming technical rejections that might otherwise lead to abandonment.

The median days to allowance is 1466. This figure shows that the path to a patent grant typically spans about four years. Given the 40.5 percent interview lift, early and frequent communication might be essential for navigating the 1466-day median pendency. These metrics together provide a comprehensive view of the effort and time required to achieve a successful outcome in Art Unit 3771.
