PETROCHINA Company Limited has 3 pending office actions in Chemistry & Materials. The matters are assigned to 3 distinct examiners and 3 distinct art units, so each active matter has its own examiner and technical grouping.
VASISTH, VISHAL V is the busiest examiner, with 1 pending matter. The record supports a separate response plan for each application, with no indicated concentration requiring a portfolio-wide examiner strategy.
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.

|---|---|
| §101 + other | 1 (33%) |
| Double-patenting + other | 1 (33%) |
| Multi-statute (no §101) | 1 (33%) |
