Instituto Mexicano Del Petróleo maintains a company patent portfolio within the Chemistry & Materials technology area. The portfolio currently shows 1 pending office action. This specific matter is assigned to 1 distinct examiner, XU, JIANGTIAN. The prosecution footprint is limited to 1 distinct art unit, reflecting a concentrated examination environment. XU, JIANGTIAN serves as the busiest examiner for the company, with 1 busiest examiner pending office action.
This alignment between the 1 pending office action and the busiest examiner's workload confirms that all current USPTO engagement is managed by a single individual. For a patent practitioner, this concentration suggests that the outcome of the current portfolio activity depends entirely on the interpretation of 1 distinct examiner within 1 distinct art unit. The Chemistry & Materials focus remains consistent across this singular point of contact. This lack of examiner diversity requires a highly tailored approach to the specific preferences of the assigned official. Practitioners should prepare for a focused dialogue within this specific art unit to advance the pending matter.
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.
