Lei Fang & Associates LLC manages a portfolio in Chemistry & Materials with 369 career applications. The firm maintains a resolved allowance rate of 82.0 percent for applications that reach a final resolution. Achieving these results involves an average of 3.46 office actions per allowance. Currently, the firm has 20 pending office actions to address.
The 369 career applications and 82.0 percent allowance rate reflect the firm's practice in its primary technology area. The 3.46 average office actions per allowance provides a benchmark for expected examiner interaction during the patent acquisition process. These figures offer a data-grounded view of the firm's historical performance and current workload for practitioners evaluating the firm's Chemistry & Materials experience.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 | 2 (9%) |
| §103 only | 5 (23%) |
| §112 only | 2 (9%) |
| Double-patenting + other | 2 (9%) |
| Multi-statute (no §101) | 10 (45%) |
| No statute on record | 1 (5%) |
