Cytek Biosciences Inc. currently manages 5 pending office actions in the Biotechnology & Pharmaceuticals technology area. These 5 actions are distributed across 5 distinct examiners and 4 distinct art units, showing a high degree of dispersion. This suggests that the company's biotechnology innovations are being reviewed by several different technical groups at the patent office, each with its own specific focus and examination standards.
The busiest examiner for the portfolio is IVICH, FERNANDO NMN, who is responsible for 1 pending office action. Because each of the 5 pending actions is assigned to a different examiner, there is no concentration of workload under any single individual. This requires practitioners to adapt to five different examination styles and sets of preferences simultaneously. The lack of examiner overlap means that every pending matter represents a unique prosecution track.
The involvement of 4 distinct art units indicates that the 5 pending office actions cover a variety of technical sub-fields within biotechnology. With 5 distinct examiners involved, the company must manage five separate prosecution timelines. Success in this environment depends on a coordinated effort to address the unique requirements of each examiner across the 4 different art units currently engaged with the portfolio. Practitioners should ensure that the strategy for each of the 5 pending actions is tailored to the specific examiner assigned.
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 |
|---|---|
| Double-patenting + other | 2 (40%) |
| Multi-statute (no §101) | 3 (60%) |
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.
