IP & T GROUP LLP manages a very large volume of patent work in the Chemistry & Materials technology area. With 11816 career applications, the firm has extensive experience across a wide array of chemical and material technologies. Its resolved allowance rate pct of 95.86 indicates an exceptionally high level of success in obtaining patent protection for its clients on a massive scale. This performance metric highlights the firm's ability to maintain quality across a high-volume portfolio.
The firm's current workload includes 233 pending office actions, reflecting a high level of ongoing prosecution activity. To achieve its grants, the firm navigates an avg office actions per allowance of 2.59. This figure suggests a relatively efficient prosecution cycle for the volume of applications handled. For practitioners, the 95.86 resolved allowance rate pct and 2.59 avg office actions per allowance provide a benchmark for the firm's performance and efficiency across its 11816 career applications. These data points help define the firm's operational standards in the Chemistry & Materials sector.
Based on the USPTO statutory response window for each pending office action. 79 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. 79 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 | 4 (1%) |
| §101 + other | 5 (2%) |
| §103 only | 128 (41%) |
| §102 only | 21 (7%) |
| §112 only | 12 (4%) |
| Double-patenting only | 3 (1%) |
| Double-patenting + other | 14 (4%) |
| Multi-statute (no §101) | 127 (40%) |
| No statute on record | 2 (1%) |
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.
