Idemitsu Kosan Co.,ltd. currently manages 88 pending office actions within the Chemistry & Materials technology area. These actions are distributed across 69 distinct examiners, which is a smaller number than the total 88 pending office actions. The portfolio spans 31 distinct art units, indicating a broad technical range for the company's filings. DEGUIRE, SEAN M is the busiest examiner, currently handling 5 pending office actions.
The 69 distinct examiners involved in these 88 pending office actions mean that many examiners are responsible for more than one case. This distribution requires the company to adapt to many different examination styles across the 31 distinct art units. DEGUIRE, SEAN M, with 5 pending office actions, represents a point of concentration in the portfolio. Practitioners should note that the 88 pending office actions are spread across many different technical groups, necessitating a versatile prosecution strategy.
With 31 distinct art units in play, the company must ensure consistency in its technical arguments across the Chemistry & Materials sector. The 69 distinct examiners provide a broad base of feedback, which can be used to refine future filings. DEGUIRE, SEAN M is the busiest examiner with 5 pending office actions, making their specific preferences a key factor for those particular cases.
Based on the USPTO statutory response window for each pending office action. 28 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. 28 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.
