3 pending office actions • 3 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready
Tanaka Chemical Corporation currently manages 3 pending office actions within the Chemistry & Materials technology area. These matters are distributed among 3 distinct examiners, indicating that each application is being reviewed by a different individual. The prosecution is organized across 3 distinct art units, suggesting that each of the 3 pending office actions falls into a unique technical sub-category.
The busiest examiner for the portfolio is NGUYEN, HAIDUNG D, who is responsible for 1 busiest examiner pending office action. This confirms that the workload is perfectly distributed, as each of the 3 distinct examiners is handling exactly one of the company's pending matters. No single examiner currently manages more than one of the 3 pending office actions in the Chemistry & Materials sector.
The use of 3 distinct art units for 3 pending office actions indicates a high degree of technical diversity within the Chemistry & Materials field. With 3 distinct examiners involved, the company must account for a wide variety of examination styles. The presence of 3 distinct examiners for 3 pending office actions requires the company to maintain several simultaneous dialogues with the patent office while following the standards of 3 distinct art units.
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.
