Tianma Japan, Ltd. currently has 3 pending office actions in the Chemistry & Materials technology area. These matters are distributed among 3 distinct examiners and 2 distinct art units. KIM, SUN U is the busiest examiner with 1 pending office action, which is consistent with the other examiners in the portfolio, as each handles exactly 1 pending office action.
The distribution of 3 pending office actions across 3 distinct examiners suggests that the company's filings are being reviewed independently. However, the concentration in 2 distinct art units indicates that some applications fall within the same specialized group. This structure requires the practitioner to manage 3 different examiner relationships while potentially addressing similar procedural standards in the 2 art units involved.
With 3 pending office actions, the company's prosecution workload is spread across multiple individuals, including KIM, SUN U with 1 pending action. This ensures that no single examiner's docket creates a bottleneck for the entire portfolio. The involvement of 3 distinct examiners and 2 distinct art units provides a balanced environment for the 3 pending office actions currently under review.
Based on the USPTO statutory response window for each pending office action. 2 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.
