Portfolio overview

AIR Products AND Chemicals, Inc. has been granted 353 US utility patents between 2015 and 2025, placing AIR Products AND Chemicals, Inc. at rank #1,200 across all assignees tracked by PlainPatent. This portfolio spans 137 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.2 claims per patent with primary concentration in B01D (SEPARATION). As a US Corporation, AIR Products AND Chemicals, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, AIR sits between Audio-technica Corporation (354 patents, rank #1,196) and Praxair Technology, Inc. (352 patents, rank #1,204) - the closest US assignees by grant volume. The composite Innovation Score of 60.7/100 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 137 grants, compared with 216 in the 2015–2019 window, a -37% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 Products AND Chemicals, Inc.'s 16.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark AIR Products AND Chemicals, Inc. 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.
