Analysis

Lorena R Feacher examines cases in Tech Center 3600 and Art Unit 2141, having reached a resolution in 417 cases. Her allowance rate is 28.5 percent. This relatively low rate indicates a challenging prosecution environment where a majority of applications do not reach allowance. Practitioners should be prepared for a rigorous examination process, as the 28.5 percent rate suggests a high threshold for patentability.

However, the interview lift is 32.1 percent. This is a significant statistic because it shows that interviews significantly improve the chances of success. In fact, the lift of 32.1 percent is higher than the base allowance rate of 28.5 percent, making interviews a vital component of any strategy for her docket. For the 417 resolved cases, the data strongly advocates for direct engagement with the examiner to overcome rejections.

The median days to allowance is 1703. This long duration suggests that successful applications undergo extensive examination. Given the 417 resolved cases, practitioners should be prepared for a lengthy process when appearing before this examiner. The 1703-day median reflects the persistence required to achieve a grant in an environment where the allowance rate is 28.5 percent.
