Roche Sequencing Solutions Inc. has 29 pending office actions in Biotechnology & Pharmaceuticals. The portfolio spans 26 distinct examiners and 14 distinct art units, showing substantial examiner diversity across a defined group of biotechnology examination areas.
QIAN, SHIZHI is the busiest listed examiner, with 2 pending matters. The limited concentration means that counsel should manage the docket through coordinated technology and disclosure positions, while maintaining separate records for the many examiner assignments.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 | 6 (24%) |
| §103 only | 3 (12%) |
| §112 only | 1 (4%) |
| Double-patenting only | 3 (12%) |
| Double-patenting + other | 4 (16%) |
| Multi-statute (no §101) | 7 (28%) |
| No statute on record | 1 (4%) |
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.
