Nalux Co. Ltd. currently has 4 pending office actions within the Semiconductors, Circuits & Optics technology area. These matters are distributed among 4 distinct examiners, creating a direct one to one relationship between the number of pending actions and the number of examiners involved. Additionally, the portfolio is spread across 4 distinct art units, which means each pending case is being evaluated by a different specialized group within the patent office.
CATTANACH, COLIN J is the busiest examiner for this portfolio, holding 1 pending office action. Because there are 4 pending office actions in total, no single examiner or art unit dominates the current workload. This distribution across the distinct art units within Semiconductors, Circuits & Optics suggests that the company's recent filings cover a variety of specific sub-technologies. Practitioners should prepare for unique sets of examiner expectations, as the distinct examiners likely have different approaches to the pending office actions. The lack of concentration among the 4 distinct examiners means that each matter requires an independent prosecution strategy.
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 (25%) |
| Multi-statute (no §101) | 3 (75%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
