Leedarson Lighting Co. Ltd. operates a company patent portfolio within the Semiconductors, Circuits & Optics technology area. The portfolio currently has 6 pending office actions, which are distributed across 6 distinct examiners. This direct ratio between the pending actions and the 6 distinct examiners suggests a broad distribution of the workload across different individuals at the patent office.
Examination for these filings is spread across 3 distinct art units, indicating that the technology within the Semiconductors, Circuits & Optics area spans multiple specialized groups. TSION M TUMEBO is the busiest examiner for the portfolio, though this examiner is only responsible for 1 busiest examiner pending office action. This reflects a fragmented prosecution environment where no single examiner holds a majority of the 6 pending office actions.
The presence of 3 distinct art units requires a prosecution strategy that accounts for varying standards and practices across different technical divisions. Because there are multiple examiners involved, the company must manage several simultaneous dialogues. Even the busiest examiner, TSION M TUMEBO, only handles 1 busiest examiner pending office action, highlighting the diverse range of perspectives currently reviewing the portfolio.
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.
| Bucket | Cases |
|---|---|
| §103 only | 2 (33%) |
| Multi-statute (no §101) | 4 (67%) |
