Analysis

Illinois Tool Works Inc. has 248 pending office actions in Transportation, E-Commerce & Mechanical Systems. The portfolio involves 193 examiners and 82 art units, creating a wide operational footprint across the technology area.

SAETHER, FLEMMING is the busiest examiner, with 6 pending matters. The identifiable concentration is small within the overall docket, so a single-examiner strategy would not address most matters.

Prosecution management should combine centralized deadline and status controls with technical ownership by art unit. Recurring issues may be identified across the examiner population, but each response still requires attention to the assigned examination context.
