Calfee, Halter & Griswold LLP reports 150 pending office actions in Chemistry & Materials and 11969 career applications. Its resolved allowance rate is 86.59%, with an average of 2.98 office actions per allowance.
The pending docket shows a large current examination workload, while the application total supplies substantial historical context for the reported outcome rate. The office-action average measures examination activity associated with allowances. For practitioners, the profile combines scale, historical results, and response-effort information useful for workload planning and prosecution review.
Based on the USPTO statutory response window for each pending office action. 42 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. 42 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 | 3 (2%) |
| §101 + other | 9 (6%) |
| §103 only | 53 (36%) |
| §102 only | 9 (6%) |
| §112 only | 1 (1%) |
| Double-patenting only | 5 (3%) |
| Double-patenting + other | 10 (7%) |
| Multi-statute (no §101) | 57 (39%) |
How the docket's pending cases split across USPTO tech-center bands.
