Tech Center 2900 • Art Units: 2935

This examiner grants 98% of resolved cases

Analysis

Erin Faith Keister is an examiner in Tech Center 2900 and Art Unit 2935. She has 62 resolved cases with an allowance rate of 98.4 percent. The median days to allowance is 624, which is the timeline for patent prosecution under her review. This duration is a key metric for applicants planning their intellectual property strategy.

The interview lift of 2.5 percent is minimal, which is expected given that the baseline allowance rate of 98.4 percent is already high. There is limited room for an interview to further increase the probability of success. With 62 resolved cases, the examiner's record is favorable for applicants. The 624-day median timeline suggests the path to allowance, and the 2.5 percent lift indicates that while interviews are an option, they are not a requirement for a positive outcome in this art unit. Practitioners can expect a successful prosecution process based on the 98.4 percent rate and the efficient 624-day median.
