Toyo Kohan Co., Ltd. has 6 pending office actions within the Chemistry & Materials technology area. These actions are spread across 6 distinct examiners, meaning that no two pending matters are being reviewed by the same person. Additionally, these cases are distributed among 4 distinct art units, showing a level of technical variety within the company's material science filings. This distribution requires the company to manage 6 different examiner relationships across the 4 distinct art units.
CHRISTY, KATHERINE A is identified as the busiest examiner, currently managing 1 pending office action. With 6 distinct examiners for 6 total actions, the portfolio's workload is spread across the patent office staff. This lack of concentration means that practitioners must be prepared to address the specific preferences of 6 different examiners while adhering to the technical standards of the 4 distinct art units involved.
Based on the USPTO statutory response window for each pending office action. 3 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 3 of the docket's apps have a known mailing date.
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.
