Portfolio overview

NOVA Chemicals (international) S.a. has been granted 280 US utility patents between 2015 and 2025, placing NOVA Chemicals (international) S.a. at rank #1,483 across all assignees tracked by PlainPatent. This portfolio spans 59 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.3 claims per patent with primary concentration in C08F (MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS). As a Foreign Corporation, NOVA Chemicals (international) S.a. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, NOVA sits between Anritsu Company (280 patents, rank #1,479) and Astrazeneca AB (279 patents, rank #1,487) - the closest US assignees by grant volume. The composite Innovation Score of 61.0/100 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 147 grants, compared with 133 in the 2015–2019 window, a +11% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. NOVA Chemicals (international) S.a.'s 20.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 59 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NOVA Chemicals (international) S.a. against peers pursuing similar technology classes.
