Halliburton Energy Services Inc. has 182 pending office actions in the Transportation, E-Commerce & Mechanical Systems technology area. These actions are assigned to 126 distinct examiners, indicating that the company interacts with many individuals at the patent office. The portfolio is distributed across 47 distinct art units, which requires the legal team to manage various technical and procedural requirements.
The examiner HALL, KRISTYN A is responsible for 6 pending office actions. While this is a concentration of work, the majority of the 182 pending office actions are spread across other assigned professionals. Practitioners should monitor the outcomes of the 6 actions under HALL, KRISTYN A to identify potential trends that might affect other matters within the Transportation, E-Commerce & Mechanical Systems area.
With 47 distinct art units involved, the company must ensure that its prosecution strategy is consistent across different technical fields. The involvement of 126 distinct examiners means that the company faces a variety of examination styles. Managing the current workload effectively requires a coordinated approach that accounts for the specific standards of the assigned art units and the individual perspectives of the examiners, including the 6 actions assigned to HALL, KRISTYN A.
Based on the USPTO statutory response window for each pending office action. 53 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. 53 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 | 13 (7%) |
| §101 + other | 37 (20%) |
| §103 only | 51 (28%) |
| §102 only | 9 (5%) |
| §112 only | 6 (3%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 4 (2%) |
| Multi-statute (no §101) | 64 (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.
