BIRCH STEWART KOLASCH & BIRCH, LLP has 119,563 career applications and 2,021 pending office actions in Chemistry & Materials. The profile reflects a very large recorded application history and a substantial current docket, indicating extensive ongoing activity in this technology area.
The resolved allowance rate is 85.79%, with an average of 3.05 office actions per allowance. The allowance rate describes resolved outcomes across the reported record, while the average indicates office-action interaction associated with allowed matters. Given the scale of the application history and pending docket, practitioners should use these figures as portfolio-level context and supplement them with matter-specific review of technical subject matter, claim strategy, and open-action status.
Based on the USPTO statutory response window for each pending office action. 482 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. 482 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 | 22 (1%) |
| §101 + other | 157 (8%) |
| §103 only | 755 (37%) |
| §102 only | 128 (6%) |
| §112 only | 86 (4%) |
| Double-patenting only | 18 (1%) |
| Double-patenting + other | 57 (3%) |
| Multi-statute (no §101) | 808 (40%) |
| No statute on record | 8 (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.
