Analysis

AMSTER, ROTHSTEIN & EBENSTEIN LLP has 148 pending office actions in Biotechnology & Pharmaceuticals and 11,093 career applications. Its resolved allowance rate is 87.6%, with an average of 3.1 office actions per allowance. The figures reflect a large prosecution base and an active unresolved docket.

The allowance rate provides a historical outcome measure, while the office-action average indicates that allowance commonly follows multiple examination interactions. For practitioners, this profile supports detailed review of claim amendments, written responses, and technology-specific prosecution patterns. The pending workload also calls for prioritization by deadline and by the potential impact of unresolved matters on broader biotechnology or pharmaceutical portfolios.

Written from this page's own data; every figure is computed from USPTO records and verified before publication.
