Company patents

Rhodia Operations

Rhodia Operations' patent strategy appears to be undergoing a significant shift, with a notable decline across almost all categories in 2025 and so far in 2026, including a 100% year-over-year drop in Functional Materials (LCD, Lubricants) and Polymer Additives in 2026. While Polymer Additives saw an emerging focus with a 133.3% YoY growth in 2024, the overall trend suggests a broad reprioritization away from many previously active areas, with only Compounds Containing Metals showing any patent activity so far in 2026.
