Wanhua Chemical Group Co., Ltd. has 3 pending office actions in the Chemistry & Materials technology area. These actions are assigned to 3 distinct examiners across 2 distinct art units. ZHANG, RUIYUN is the busiest examiner, managing 1 pending action. This distribution indicates that the company's chemical filings are spread across multiple administrative groups at the USPTO.
The distribution of 3 pending office actions across 2 distinct art units shows some technical variety within the chemical field. Each of the 3 distinct examiners is responsible for 1 pending action, including the busiest examiner. This structure indicates that the company's current prosecution efforts are spread across different administrative sections, though some concentration exists within the 2 distinct art units. Practitioners should be prepared to manage 3 different examiner styles across the 3 pending office actions. Because the workload is split, no single examiner is overwhelmed by the company's current filings.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 |
