Cellares Corporation has 6 pending office actions in Chemistry & Materials. The matters involve 6 distinct examiners across 4 distinct art units. The one-to-one relationship between actions and examiners means every pending matter has a separate examiner assignment, while the smaller number of art units shows that some examination activity is grouped by technology area.
ZHU, JIANJIAN is the busiest examiner, with 1 pending matter. That distribution limits the value of treating one examiner as the central prosecution contact. Counsel should instead map claim issues, cited art, and response timing separately for each examiner, while using the art-unit grouping to identify recurring technical or procedural themes.
The docket calls for coordinated portfolio oversight rather than a single examiner-focused strategy. Art-unit patterns may help organize that review, but the available data does not identify whether the actions share claim scope or substantive grounds.
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.
| Bucket | Cases |
|---|---|
| §103 only | 2 (33%) |
| §102 only | 1 (17%) |
| Double-patenting + other | 1 (17%) |
| Multi-statute (no §101) | 2 (33%) |
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.
