Analysis

Murata Machinery Ltd. has 16 pending office actions in the Transportation, E-Commerce & Mechanical Systems technology area. The portfolio is spread across 16 distinct examiners and 12 distinct art units. This distribution of examiners and pending actions indicates a decentralized prosecution environment. For a company with 16 pending office actions, this lack of examiner overlap means that no single examiner's habits can be used to predict the outcome of more than one case. Practitioners must prepare for 16 different sets of examiner preferences and 12 different art unit standards.

NGUYEN, CUONG H is the busiest examiner, with 1 pending office action. While NGUYEN, CUONG H is the busiest, they only handle a portion of the total 16 pending office actions. The 12 distinct art units involved suggest that the company's mechanical innovations are technically diverse, requiring a broad range of expertise from the legal team. Navigating 12 distinct art units means the company must adhere to various internal USPTO policies and technical interpretations. With 16 distinct examiners, the company should expect a variety of prior art citations and legal rejections across the 16 pending office actions.
