4 pending office actions • 4 art units • 4 examiners • 0 of 4 (0%) have an AI response strategy ready
Carbon Clean Solutions Limited manages 4 pending office actions in the Chemistry & Materials technology area. These matters are distributed among 4 distinct examiners and 3 distinct art units. SHAO, PHILLIP Y is the busiest examiner, currently handling 1 pending action.
The ratio of 4 pending office actions to 4 distinct examiners shows that no examiner is managing multiple active cases for the company. However, the involvement of 3 distinct art units indicates that some of these examiners are grouped within the same technical division. With a busiest examiner pending count of 1, the portfolio's current workload is spread thinly across the patent office's personnel.
For a practitioner, this dispersion across 4 distinct examiners means that the company must maintain four separate prosecution strategies. The use of 3 distinct art units suggests that while the technology is within the Chemistry & Materials sector, it spans multiple specialized subgroups. This variety provides a broad range of examiner feedback, reducing the risk that a single official's interpretation will negatively impact the entire portfolio of 4 pending office actions.
Based on the USPTO statutory response window for each pending office action. 1 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.
