Portfolio overview

Air Liquide Advanced Technologies U.s. Llc has been granted 39 US utility patents between 2016 and 2025, placing Air Liquide Advanced Technologies U.s. Llc at rank #8,159 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.4 claims per patent with primary concentration in B01D (SEPARATION). As a US Corporation, Air Liquide Advanced Technologies U.s. Llc is one of the more focused assignees in the PatentsView dataset. By volume, Air sits between Asahi Yukizai Corporation (39 patents, rank #8,155) and Apollo Tyres Global R&D B.v. (39 patents, rank #8,163) - the closest US assignees by grant volume. The composite Innovation Score of 46.4/100 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 24 grants, compared with 15 in the 2015–2019 window, a +60% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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. Air Liquide Advanced Technologies U.s. Llc's 16.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Air Liquide Advanced Technologies U.s. Llc against peers pursuing similar technology classes.
