Analysis

The Wistar Institute has 21 pending office actions in Biotechnology & Pharmaceuticals. The matters involve 21 distinct examiners across 15 distinct art units, showing a large and widely distributed prosecution portfolio. This scale requires systematic docket controls, consistent recordkeeping, and an approach that separates portfolio-wide policy from application-specific decisions.

SHIAO, REI TSANG is the busiest examiner, with 1 pending matter. The data therefore shows no concentration of the pending matters in a single examiner, even though the portfolio has substantial overall activity.

Counsel should use centralized review to identify recurring claim, written-description, and prior-art themes across the 15 art units. Responses, interviews, and amendment decisions should then be tailored to each examiner, because the 21 matters are distributed across 21 examiner assignments.
