Portfolio overview

ZURN Industries, Llc has been granted 119 US utility patents between 2015 and 2024, placing ZURN Industries, Llc at rank #3,170 across all assignees tracked by PlainPatent. This portfolio spans 49 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in E03F (SEWERS; CESSPOOLS). As a US Corporation, ZURN Industries, Llc is one of the more focused assignees in the PatentsView dataset. By volume, ZURN sits between Titan Medical Inc. (119 patents, rank #3,166) and Consumerinfo.com, Inc. (118 patents, rank #3,174) - the closest US assignees by grant volume. The composite Innovation Score of 57.7/100 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 68 grants, compared with 51 in the 2015–2019 window, a +33% 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. ZURN Industries, Llc's 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 49 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZURN Industries, Llc against peers pursuing similar technology classes.
