Varian Inc. maintains a portfolio with 22 pending office actions in the Medical Devices & Mechanical Engineering technology area. This workload is assigned to 22 distinct examiners. The prosecution spans 13 distinct art units, reflecting the technical distribution of the company's Medical Devices & Mechanical Engineering filings. This distribution across 13 distinct art units indicates that the company's active matters are subject to the specific standards of those assigned art units at the patent office.
The busiest examiner for this portfolio is NGUYEN, VI X, who is responsible for 1 pending office action. This count of 1 pending office action for the busiest examiner is part of the total 22 pending office actions. With 22 distinct examiners involved, practitioners managing this portfolio must coordinate across individual examiner preferences. The fact that NGUYEN, VI X handles this workload highlights the distribution of the current prosecution pipeline. This requires a strategy that accounts for the requirements of the 22 distinct examiners across the 13 distinct art units.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 |
|---|---|
| §101 + other | 3 (18%) |
| §103 only | 6 (35%) |
| §102 only | 1 (6%) |
| Multi-statute (no §101) | 7 (41%) |
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.
