Analysis

White & Case LLP is active in Biotechnology & Pharmaceuticals, with 2805 career applications and 10 pending office actions. The profile therefore combines a broad application base with a limited group of currently pending examination matters. Its resolved allowance rate is 81.0%, indicating that allowance was recorded for a majority of resolved applications.

Allowances average 2.65 office actions. This suggests that examination commonly includes multiple actions before allowance, even though the average is below three actions. For practitioners, the allowance rate supplies an outcome measure, while the action average describes prosecution activity associated with that outcome. The pending-action figure should be considered separately when evaluating current docket needs.

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