Iovance Biotherapeutics Inc. has 18 pending office actions in the Biotechnology & Pharmaceuticals technology area. Similar to other large portfolios, there is a high level of examiner variety, with 18 distinct examiners assigned to the 18 pending actions. This distribution implies that each pending matter is being reviewed by a different individual, preventing the company from consolidating its prosecution efforts under a few key examiners.
The 18 pending office actions are spread across 11 distinct art units. This indicates that the Biotechnology & Pharmaceuticals portfolio is technically diverse, touching on many different specialized groups within the patent office. MOSELEY II, NELSON B is the busiest examiner, but like all other examiners in this set, they handle only 1 busiest examiner pending action. Practitioners must therefore prepare for 18 unique examination perspectives across 11 different art units to manage this portfolio effectively, as no single official dominates the 18 pending matters.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 (12%) |
| §103 only | 2 (12%) |
| Double-patenting + other | 9 (53%) |
| Multi-statute (no §101) | 4 (24%) |
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.
