Okuma Corporation currently manages 6 pending office actions within its company patent portfolio, focused on the Medical Devices & Mechanical Engineering technology area. These 6 pending actions are distributed across 2 distinct art units, suggesting that the company's mechanical innovations are concentrated in two primary technical groups. This arrangement allows the company to develop specialized strategies for each of the 2 distinct art units involved.
The prosecution workload is handled by 6 distinct examiners, matching the total number of 6 pending office actions. This 1 to 1 ratio ensures that each application is being reviewed by a different individual, providing a wide range of perspectives on the company's mechanical claims. CHANG, VINCENT WEN-LIANG is identified as the busiest examiner, currently managing 1 pending office action for the corporation.
The 6 pending office actions represent the current active pipeline for Okuma Corporation in the Medical Devices & Mechanical Engineering sector. With 6 distinct examiners and 2 distinct art units, the prosecution environment is administratively diverse but technically focused. CHANG, VINCENT WEN-LIANG, as the busiest examiner with 1 pending action, is one of several key figures in the company's ongoing efforts to secure patent protection.
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 |
|---|---|
| §103 only | 1 (17%) |
| §102 only | 1 (17%) |
| §112 only | 1 (17%) |
| Multi-statute (no §101) | 3 (50%) |
