LEYDIG VOIT & MAYER, LTD has 23,821 career applications in Chemistry & Materials and 796 pending office actions. The figures reflect an extensive prosecution history and a large active docket requiring structured management.
The resolved allowance rate is 99.49%, and the average is 3.88 office actions per allowance. The allowance figure describes resolved outcomes, while the action average shows the examination activity associated with matters that reached allowance.
For practitioners, the size of the pending docket makes prioritization and response tracking important. The historical measures provide broad context, but they do not replace application-level analysis of claim scope, cited art, interviews, or outstanding procedural issues.
Based on the USPTO statutory response window for each pending office action. 200 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. 200 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 | 12 (1%) |
| §101 + other | 90 (11%) |
| §103 only | 255 (32%) |
| §102 only | 33 (4%) |
| §112 only | 44 (5%) |
| Double-patenting only | 8 (1%) |
| Double-patenting + other | 40 (5%) |
| Multi-statute (no §101) | 319 (40%) |
| No statute on record | 5 (1%) |
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.
