Halliburton Energy Services Inc. has 189 pending office actions in Transportation, E-Commerce & Mechanical Systems. The matters span 124 distinct examiners and 52 distinct art units, indicating a large portfolio distributed across numerous examination channels.
HALL, KRISTYN A is the busiest examiner, with 6 pending matters. That docket represents one recurring assignment within the larger workload. Counsel should use centralized issue and deadline tracking while maintaining examiner-specific strategies for the recurring matters.
Based on the USPTO statutory response window for each pending office action. 50 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. 50 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 | 11 (6%) |
| §101 + other | 33 (19%) |
| §103 only | 52 (29%) |
| §102 only | 8 (4%) |
| §112 only | 7 (4%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 3 (2%) |
| Multi-statute (no §101) | 63 (35%) |
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.
