Company patents
Chevron Phillips Chemical Company LP
Chevron Phillips Chemical Company LP's patent strategy shows a surprising broad decline across its core materials categories, with 'Catalysts & Reactors' (50.3% of portfolio) and 'Polymer Synthesis (Polymerization)' (46.7% of portfolio) both experiencing significant drops of -47.8% and -22.0% respectively in 2025. This suggests a shifting priority away from these historically dominant areas, despite a brief emerging focus in 'Petroleum / Hydrocarbon Refining' which saw a +42.9% YoY growth in 2024 before a sharp decline in 2025.
