BOLT THREADS, INC. manages a portfolio in the Biotechnology & Pharmaceuticals technology area with 6 pending office actions. These actions are distributed among 6 distinct examiners, meaning each pending case is being reviewed by a different individual. This distribution suggests a lack of examiner-level concentration in the current prosecution workload. The company's active filings are being evaluated by a diverse group of reviewers across the patent office.
The 6 pending office actions are spread across 5 distinct art units. This indicates that at least two of the actions are being handled within the same art unit, while the rest are in separate units. JIANFENG SONG is the busiest examiner for the portfolio, currently managing 1 pending office action. This confirms that the workload is evenly split, with each of the 6 distinct examiners handling exactly 1 of the pending office actions. No single examiner has a majority of the cases.
For practitioners, this portfolio requires managing multiple relationships across 5 distinct art units. While the examiners are all different, the slight concentration in art units may allow for some shared insights into unit-specific practices. However, with 6 pending office actions and 6 distinct examiners, the primary challenge is the diversity of individual examiner preferences within the Biotechnology & Pharmaceuticals sector. Strategy should focus on identifying commonalities within the 5 distinct art units while addressing each examiner's unique requirements.
Based on the USPTO statutory response window for each pending office action. 3 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 3 of the docket's apps have a known mailing date.
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 | 3 (60%) |
| Multi-statute (no §101) | 2 (40%) |
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.
