Analysis

Saul Ewing LLP (Philadelphia) reports 5469 career applications, 164 pending office actions, and a Biotechnology & Pharmaceuticals focus. The application history and pending workload show an established practice with substantial continuing prosecution activity in a technically demanding area. The pending-action figure is a current workload measure, while the application total reflects the broader record.

The resolved allowance rate is 81.32%, and the average is 3.93 office actions per allowance. These measures provide separate views of outcome and examination effort. Practitioners can use the allowance figure when evaluating historical resolution patterns and the action average when planning response resources, but neither replaces review of the relevant technology and rejection grounds.

For biotechnology and pharmaceutical matters, that review should connect claim scope to written description, enablement, prior art, and therapeutic evidence. The profile supports benchmarking within this practice, while individual prosecution histories remain necessary for matter-specific strategy.

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