Portfolio overview

Airgas, Inc. has been granted 20 US utility patents between 2017 and 2025, placing Airgas, Inc. at rank #14,459 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.6 claims per patent with primary concentration in F17C (VESSELS FOR CONTAINING OR STORING COMPRESSED, LIQUEFIED OR SOLIDIFIED GASES; FIXED-CAPACITY GAS-HOLDERS; FILLING VESSELS WITH, OR DISCHARGING FROM VESSELS, COMPRESSED, LIQUEFIED, OR SOLIDIFIED GASES). As a US Corporation, Airgas, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Airgas sits between Advaxis, Inc. (20 patents, rank #14,455) and Aleris Rolled Products Germany Gmbh (20 patents, rank #14,463) - the closest US assignees by grant volume. The composite Innovation Score of 39.0/100 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 14 grants, compared with 6 in the 2015–2019 window, a +133% 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. Airgas, Inc.'s 9.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Airgas, Inc. against peers pursuing similar technology classes.
