Analysis

Riken Keiki Co. Ltd. has 2 pending office actions situated in the Semiconductors, Circuits & Optics technology area. These filings are concentrated within 1 distinct art unit, suggesting a specific technical focus for the company's current U.S. patent activities. Because the portfolio involves 1 distinct examiner, the company faces a consolidated prosecution environment where an examiner's interpretation of the prior art will be decisive for all current matters.

FRANK, RODNEY T serves as the busiest examiner, overseeing the 2 pending office actions. This means that the company's current pending workload is assigned to him, creating a high level of examiner-specific risk. Practitioners should focus their efforts on the specific tendencies of FRANK, RODNEY T, as his decisions will impact the entirety of the pending office actions. The lack of diversity across art units or examiners simplifies the administrative burden but increases the importance of a successful relationship with this examiner in the Semiconductors, Circuits & Optics field.
