Proterial Ltd. has 41 pending office actions in Chemistry & Materials. The matters span 35 distinct examiners and 25 art units, reflecting broad portfolio distribution across the examination organization.
MAYO III, WILLIAM H is associated with 3 pending matters, providing a recurring examiner relationship within an otherwise widely dispersed docket. Portfolio management should combine centralized tracking of technical themes with examiner- and art-unit-specific response planning.
The scale and dispersion make docket controls particularly important. Counsel should identify repeated claim issues, preserve consistent disclosure positions, and separately monitor the many art-unit assignments so that procedural developments are not overlooked.
Based on the USPTO statutory response window for each pending office action. 8 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. 8 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 | 1 (2%) |
| §103 only | 25 (58%) |
| §102 only | 4 (9%) |
| §112 only | 1 (2%) |
| Multi-statute (no §101) | 12 (28%) |
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.
