Birchwood IP- CHK001 operates in the Biotechnology & Pharmaceuticals field with 498 career applications. The firm has achieved a resolved allowance rate of 94.33 percent. Currently, the firm has 6 pending office actions, which represent its active workload relative to its 498 career applications.
The firm's efficiency is reflected in an average of 1.01 office actions per allowance. This 1.01 average indicates a direct prosecution strategy. For practitioners, the 94.33 percent resolved allowance rate and the 1.01 office actions per allowance metric highlight the firm's performance in the Biotechnology & Pharmaceuticals sector. The 498 career applications provide a history of results, and the 6 pending office actions show the firm's current activity in securing patent grants. The 1.01 office actions per allowance figure suggests that many applications reach resolution with minimal examiner interaction, providing a benchmark for expected prosecution timelines.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 | 1 (10%) |
| §103 only | 3 (30%) |
| §102 only | 1 (10%) |
| Multi-statute (no §101) | 5 (50%) |
