Portfolio overview

Solvay Sa has been granted 164 US utility patents between 2015 and 2025, placing Solvay Sa at rank #2,386 across all assignees tracked by PlainPatent. This portfolio spans 85 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.8 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Solvay Sa is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Solvay sits between NIO Technology (anhui) Co., Ltd (164 patents, rank #2,382) and Univation Technologies, Llc (164 patents, rank #2,390) - the closest US assignees by grant volume. The composite Innovation Score of 55.2/100 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 69 grants, compared with 95 in the 2015–2019 window, a -27% 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. Solvay Sa's 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 85 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Solvay Sa against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
