THE H.T. THAN LAW GROUP focuses on Chemistry & Materials, with 542 career applications and 6 pending office actions. The resolved allowance rate is 86.39%, providing a favorable allowance outcome within the recorded prosecution history.
Allowed matters average 3.49 office actions. That measure suggests that examination often continues through multiple responses before resolution, so practitioners may need to budget for sustained claim negotiation rather than assume early disposition. The pending docket adds a current workload signal, while the application total gives scale to the outcome rate.
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 |
|---|---|
| Double-patenting + other | 3 (50%) |
| Multi-statute (no §101) | 3 (50%) |
