Buchanan Ingersoll & Rooney PC has 624 pending office actions in Chemistry & Materials and 54163 career applications. The pending figure indicates a substantial active examination workload, while the application record shows an extensive prosecution base in this technology area.
The resolved allowance rate is 84.89%, and the average is 3.27 office actions per allowance. Resolved matters reach allowance at the reported rate, with multiple office actions commonly occurring before allowance. For practitioners, the figures support capacity planning, response prioritization, and review of chemistry and materials matters requiring sustained prosecution attention.
Based on the USPTO statutory response window for each pending office action. 141 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. 141 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 only | 10 (2%) |
| §101 + other | 70 (11%) |
| §103 only | 209 (34%) |
| §102 only | 29 (5%) |
| §112 only | 20 (3%) |
| Double-patenting only | 3 (0%) |
| Double-patenting + other | 25 (4%) |
| Multi-statute (no §101) | 253 (41%) |
| No statute on record | 1 (0%) |
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.
