Technology area: Chemistry & Materials
3 pending office actions • 3 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 6 patents granted in the last 365 days
Castrol Limited has 3 pending office actions within the Chemistry & Materials technology area. These actions are assigned to 3 distinct examiners, ensuring that each pending matter is reviewed by a unique individual. The portfolio also spans 3 distinct art units, which suggests that the company's current chemistry and materials innovations are technically diverse enough to be classified into three separate administrative groups. This variety indicates a broad front of active prosecution for the company.
The busiest examiner for the portfolio is DOUYETTE, KENNETH J, who holds 1 pending office action. Because the busiest examiner pending count is 1, the 3 pending office actions are distributed equally among the examiners. For a practitioner, this means that the prosecution strategy must be adapted to different examiners and art units. The presence of 3 distinct examiners and 3 distinct art units requires a multi-faceted approach to address the specific technical and procedural nuances of each individual pending matter.
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 (33%) |
| Double-patenting + other | 1 (33%) |
| Multi-statute (no §101) | 1 (33%) |
