Posco Silicon Solution Co. Ltd. is active in the Chemistry & Materials technology area. The company's current prosecution activity includes 1 pending office action. This matter is being handled by 1 distinct examiner, WALLS, CYNTHIA KYUNG SOO, in 1 distinct art unit. WALLS, CYNTHIA KYUNG SOO is the busiest examiner with 1 busiest examiner pending. This means that the company's immediate patent outcomes are determined by this 1 distinct examiner. The focus on 1 distinct art unit indicates a specialized technical scope within the chemistry field.
With only 1 pending office action, the portfolio is in a phase of limited but concentrated activity. Practitioners should prioritize understanding the specific requirements of the 1 distinct examiner involved. The absence of multiple examiner perspectives means there is no internal baseline for comparing examiner behavior. Every interaction with WALLS, CYNTHIA KYUNG SOO is critical, as there are no other active matters to balance the portfolio's progress. This concentration means that the company's immediate patent prospects are shaped by a single individual's interpretation within the 1 distinct art unit. For a portfolio of this scale, the administrative overhead is minimal.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
