Analysis

Zanna Maria Beharry is an examiner in Tech Center 1700 and Art Unit 1631. She has a total of 73 resolved cases, which have resulted in an allowance rate of 24.7%. This 24.7% rate suggests a rigorous examination process where applicants face significant hurdles. However, the data shows a very high interview lift of 56.4%. This 56.4% figure suggests that while the initial path to allowance is difficult, direct communication through an interview is a powerful tool for overcoming rejections compared to the 24.7% baseline.

The median days to allowance for her docket is 1508. This 1508 duration reflects a lengthy prosecution period, likely involving multiple rounds of office actions. With 73 resolved cases, the 24.7% allowance rate highlights the challenging nature of Art Unit 1631. Practitioners should strongly consider the 56.4% interview lift as a primary strategy to navigate these challenges. The 1508-day median pendency underscores the need for a persistent approach when working with Examiner Beharry in Tech Center 1700.
