Analysis

Ibiden Co., Ltd. has 18 pending office actions in Semiconductors, Circuits & Optics. The portfolio spans 17 distinct examiners and 11 distinct art units, showing broad examiner allocation with some matters sharing technical examination groupings.

THAYER, ABIGAIL MARIE is the busiest examiner, with 2 pending matters. That examiner-specific concentration is limited, so counsel should not assume that a single response model will address the entire portfolio.

Grouping matters by art unit can help identify recurring issues in semiconductor, circuit, or optical claim language. At the same time, separate examiner assignments make individualized argument development and amendment practice important for advancing each application.
