Technology area: Chemistry & Materials
3 pending office actions • 2 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 12 patents granted in the last 365 days
China National Petroleum Corporation currently manages 3 pending office actions within the Chemistry & Materials technology area. These matters are distributed across 3 distinct examiners and 2 distinct art units. This distribution suggests a focused but slightly divided prosecution strategy where the technical subject matter spans multiple specialized groups within the patent office. Practitioners should note the coordination required across 2 distinct art units for this portfolio, as different units may have varying timelines or procedural nuances.
The busiest examiner is RODD, CHRISTOPHER M, who is responsible for 1 pending office action. This indicates that the workload is evenly spread among the 3 distinct examiners, as no single individual holds more than 1 of the 3 pending office actions. Because each examiner handles a single action, the company benefits from multiple independent reviews of its technology. This arrangement ensures that the 3 pending office actions are not concentrated under a single point of failure or specific examiner bias, providing a broader perspective on the portfolio's patentability across the 2 distinct art units involved.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
