Portfolio overview

Rhodia Operations has been granted 484 US utility patents between 2015 and 2025, placing Rhodia Operations at rank #920 across all assignees tracked by PlainPatent. This portfolio spans 114 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in C09K (MATERIALS FOR MISCELLANEOUS APPLICATIONS, NOT PROVIDED FOR ELSEWHERE). As a Foreign Corporation, Rhodia Operations is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Rhodia sits between University-industry Cooperation Group OF Kyung HEE University (488 patents, rank #916) and Toyota Motor North America, Inc. (483 patents, rank #924) - the closest US assignees by grant volume. The composite Innovation Score of 60.0/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 183 grants, compared with 301 in the 2015–2019 window, a -39% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Rhodia Operations's 16.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rhodia Operations against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
