3 pending office actions • 3 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready
Young Chang Chemical Co. Ltd. operates a company patent portfolio within the Chemistry & Materials technology area. The portfolio currently has 3 pending office actions, which suggests a broader range of active prosecution than smaller portfolios in the same sector. These actions are distributed across 3 distinct examiners, showing that the company is interacting with multiple points of review within the patent office simultaneously.
The work is further spread across 3 distinct art units. This variety in art units indicates that the Chemistry & Materials innovations being pursued may span different technical subclasses or specialized examination groups. LEE, ALEXANDER N is the busiest examiner associated with the portfolio. This examiner is currently handling 1 pending office action, which is a portion of the total actions pending for the company.
The fact that the busiest examiner pending count is 1 confirms that no single examiner dominates the current workload. Instead, the prosecution is split among the distinct examiners. This distribution can provide the company with diverse perspectives from different officials within the USPTO's Chemistry & Materials divisions.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
