Analysis

Kristina Elisabeth Ly is a patent examiner in Tech Center 1600, working within Art Unit 1641. The current data for this examiner is based on 8 resolved cases. This small sample size results in an allowance rate of 37.5 percent. Practitioners should view this rate as a preliminary indicator of the examiner's tendencies, noting that the 37.5 percent figure may fluctuate as more cases are resolved in Art Unit 1641.

A significant data point is the interview lift of 100.0 percent. This suggests that every allowance granted by this examiner so far was associated with an interview. While the 37.5 percent allowance rate is relatively low, the 100.0 percent lift indicates that direct communication is an exceptionally effective strategy. Applicants should prioritize interviews to navigate the complexities of this examiner's review process.

The median days to allowance is 1086, which establishes the expected timeline for successful prosecution. With 8 resolved cases, the examiner's profile is still developing, but the 1086-day duration provides a useful benchmark. Given the 100.0 percent interview lift, practitioners have a clear tactical path to improve their chances of success despite the current 37.5 percent allowance rate. This proactive approach may be essential for overcoming rejections in Tech Center 1600.
