Analysis

COZEN O'CONNOR focuses on Transportation, E-Commerce & Mechanical Systems. Its profile shows 86 pending office actions and 19456 career applications, reflecting a substantial historical prosecution record alongside an active current docket. The volume supports formal docket controls, prioritization of matters by response urgency, and consistent review of recurring examination issues.

The resolved allowance rate is 85.66%, and the average is 3.35 office actions per allowance. Resolved matters therefore frequently reach allowance, although they may involve several rounds of examination. Practitioners can treat the aggregate result as a useful portfolio indicator while still tailoring prosecution strategy to the claims and prior-art record of each matter.
