Portfolio overview

Constellium Issoire has been granted 45 US utility patents between 2017 and 2025, placing Constellium Issoire at rank #7,250 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in C22C (ALLOYS). As a Foreign Corporation, Constellium Issoire is one of the more focused assignees in the PatentsView dataset. By volume, Constellium sits between California Expanded Metal Products Company (45 patents, rank #7,246) and Danfoss Commercial Compressors (45 patents, rank #7,254) - the closest US assignees by grant volume. The composite Innovation Score of 46.3/100 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 30 grants, compared with 15 in the 2015–2019 window, a +100% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Constellium Issoire's 15.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Constellium Issoire 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.
