57 pending office actions • 13 art units • 41 examiners • 0 of 57 (0%) have an AI response strategy ready • 56 patents granted in the last 365 days
Uop LLC maintains an exceptionally large and active company patent portfolio within the Chemistry & Materials technology area. The portfolio currently has 53 pending office actions, reflecting a massive and ongoing commitment to securing intellectual property. This volume of 53 pending office actions indicates that the company is a major innovator in the chemistry field, with a constant stream of new applications under review.
The prosecution of these 53 actions is distributed among 40 distinct examiners and 12 distinct art units. This wide distribution shows that Uop LLC's patent filings are technically diverse, requiring review by a large number of experts across many different administrative divisions. The fact that 40 distinct examiners are involved means that the company's success is spread across many individuals, providing a high degree of diversification in its prosecution outcomes.
CHONG, JASON Y is the busiest examiner for Uop LLC, currently handling 5 pending office actions. While Chong has the highest individual workload, the busiest examiner pending count of 5 is only a small fraction of the 53 total pending office actions. This means that while Chong's decisions are important, the overall health of the portfolio depends on the collective actions of 40 distinct examiners across 12 distinct art units, reflecting a complex and decentralized prosecution landscape.
Based on the USPTO statutory response window for each pending office action. 19 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. 19 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 only | 1 (2%) |
| §103 only | 20 (35%) |
| §112 only | 1 (2%) |
| Double-patenting only | 3 (5%) |
| Double-patenting + other | 2 (4%) |
| Multi-statute (no §101) | 29 (51%) |
| No statute on record | 1 (2%) |
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.
