National Oilwell Varco L.P. has 13 pending office actions in Transportation, E-Commerce & Mechanical Systems. The matters involve 13 distinct examiners and 7 distinct art units, showing broad examiner distribution with recurring activity across the art-unit structure.
DAVIS, MARY ALICE is the busiest examiner, with 1 pending matter. Because no examiner has a larger concentration, portfolio management should emphasize matter-level tracking. The 7 art units provide a practical basis for coordinating technical positions, while examiner-specific treatment remains important across the 13 assignments.
Based on the USPTO statutory response window for each pending office action. 7 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. 7 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 | 1 (10%) |
| §103 only | 1 (10%) |
| Multi-statute (no §101) | 8 (80%) |
