3D Systems Inc. has 14 pending office actions in Chemistry & Materials. The portfolio spans 14 examiners and 10 art units, indicating that every pending matter has a distinct examiner assignment while several matters share broader technical groupings.
WILLIAMS, CEDRICK S is the busiest examiner, with 1 pending matter. There is no material concentration around a single examiner in the supplied data, so docket controls and consistent claim analysis are important across the portfolio.
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.
| Bucket | Cases |
|---|---|
| §101 + other | 1 (8%) |
| §103 only | 5 (38%) |
| §112 only | 2 (15%) |
| Multi-statute (no §101) | 5 (38%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
