Analysis

Michelle Stein serves as a patent examiner in Tech Center 1700 and Art Unit 1771. She has a record of 675 resolved cases. The examiner maintains an allowance rate of 45.2 percent, which indicates that less than half of the applications reaching a final resolution result in a grant. This percentage provides a baseline for practitioners to evaluate the probability of a grant in this unit.

The data highlights a significant interview lift of 35.6 percent. This metric suggests that conducting an interview with the examiner is a highly effective strategy for moving a case toward allowance. Practitioners can use this 35.6 percent lift to justify the time and expense of direct communication, as it represents a measurable improvement in the likelihood of a positive outcome. This is a key tactical consideration for Art Unit 1771.

The median time to allowance is 1371 days. This duration represents the typical timeframe for successful applications to move from filing to issuance. With 675 resolved cases as the basis for these metrics, the profile provides a clear indication of the timeline and success rates expected. These figures help practitioners manage client expectations regarding the duration of the process in Tech Center 1700.
