Analysis

DLA PIPER LLP (US) covers Biotechnology & Pharmaceuticals and reports 65 pending office actions. Its career record contains 21180 applications, with a resolved allowance rate of 84.39% and an average of 3.7 office actions per allowance.

The historical allowance rate indicates that a majority of resolved matters reached allowance, while the action average shows that allowed matters generally involved multiple examination exchanges. The pending docket is a separate workload indicator and does not establish the eventual result of those open matters.

For practitioners, biotechnology and pharmaceutical prosecution requires coordinated attention to claim scope, disclosure support, and prior-art distinctions. The application record can support portfolio-level process review, while the open actions should be prioritized by deadline, technical significance, and the client’s objectives.

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