Lei Fang & Associates LLC has 24 pending office actions in Chemistry & Materials and 368 career applications. Its resolved allowance rate is 82.09%, with an average of 3.48 office actions per allowance.
The application history supplies context for the resolved outcome measure. The pending-action count identifies active unresolved work, while the average-action figure indicates repeated examination activity among allowed matters. Practitioners should use these metrics as a starting point for docket review and examine the underlying chemistry and materials files for the claim issues involved.
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 (8%) |
| §103 only | 6 (24%) |
| §112 only | 3 (12%) |
| Double-patenting + other | 1 (4%) |
| Multi-statute (no §101) | 13 (52%) |
