Cantor Colburn LLP - DuPont has 6 pending office actions in Chemistry & Materials. The profile reports 74576 career applications, an 88.02% resolved allowance rate, and an average of 3.15 office actions per allowance.
The pending docket identifies current examination matters for the DuPont profile. The broader historical figures provide context for outcomes and response effort, but they should not be treated as a direct measure of the six open actions. For practitioners, the record supports separate review of immediate workload and historical prosecution patterns.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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.
