Portfolio overview

Fenwal, Inc. has been granted 363 US utility patents between 2015 and 2025, placing Fenwal, Inc. at rank #1,171 across all assignees tracked by PlainPatent. This portfolio spans 60 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.8 claims per patent with primary concentration in A61M (DEVICES FOR INTRODUCING MEDIA INTO, OR ONTO, THE BODY ; DEVICES FOR TRANSDUCING BODY MEDIA OR FOR TAKING MEDIA FROM THE BODY ; DEVICES FOR PRODUCING OR ENDING SLEEP OR STUPOR). As a US Corporation, Fenwal, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Fenwal sits between Purdue Pharma L.p. (365 patents, rank #1,167) and Coupang Corp. (362 patents, rank #1,175) - the closest US assignees by grant volume. The composite Innovation Score of 61.6/100 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 204 grants, compared with 159 in the 2015–2019 window, a +28% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Fenwal, Inc.'s 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 60 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Fenwal, 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.
