Analysis

NIPRO Corporation maintains 14 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are assigned to 14 distinct examiners, creating a scenario where every pending application is under the review of a different person. This distribution requires the management of 14 unique examiner interactions across the portfolio.

The pending office actions are categorized into 8 distinct art units. This variety of art units indicates that the company's Medical Devices & Mechanical Engineering innovations span multiple technical sub-specialties. Practitioners must navigate the specific procedural and technical standards of 8 different administrative groups to successfully prosecute the pending actions.

KIM, ERIN ASA is the busiest examiner for this portfolio, currently holding 1 pending office action. Because the busiest examiner only has 1 of the 14 total actions, the portfolio is entirely decentralized at the examiner level. Prosecution success will depend on the ability to effectively communicate with many different individuals, as no single examiner holds a majority of the workload.
