Technology area: Medical Devices & Mechanical Engineering
2 pending office actions • 2 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready • 3 patents granted in the last 365 days
Cummins Ltd. is managing 3 pending office actions within the Medical Devices & Mechanical Engineering technology area. These matters are distributed among 3 distinct examiners, meaning each pending action is being reviewed by a different person. This lack of examiner overlap suggests that the company's current prosecution involves multiple independent perspectives within the patent office. With 3 pending office actions and 3 distinct examiners, the portfolio currently maintains a distribution where each matter has its own examiner.
The 3 pending actions are situated within 2 distinct art units, indicating some level of technical clustering despite the different examiners involved. The busiest examiner, CLARK, RYAN C, is assigned 1 busiest examiner pending office action. Given that the total number of pending actions is 3 and there are 3 distinct examiners, every examiner currently assigned to the portfolio holds exactly 1 action. This even distribution across 2 art units means that the prosecution strategy is currently fragmented across several points of contact, requiring the company to manage interactions with 3 different individuals. The presence of 2 distinct art units suggests that some matters share a technical classification.
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 |

| §112 only | 1 (50%) |
| Multi-statute (no §101) | 1 (50%) |
