Yunda H&H Tech (Tianjin) Co. Ltd. currently has 3 pending office actions in the Chemistry & Materials technology area. These matters are being reviewed by 3 distinct examiners across 3 distinct art units. This distribution indicates that each of the 3 pending office actions is being handled independently by a different official in a different administrative group.
KATINA N HENSON is the busiest examiner for this portfolio, with 1 busiest examiner pending action currently assigned to her. Since there are 3 distinct examiners for the 3 pending office actions, the workload is evenly spread. This prevents any single examiner from having a dominant influence over the company's current Chemistry & Materials filings.
The presence of 3 distinct art units suggests that the company's technical focus is divided into three separate sub-categories. Coordinating the prosecution of these active matters requires the legal team to address the specific requirements of 3 distinct examiners. This structure ensures that the progress of one application is not directly tied to the same examiner or art unit as the others.
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.
