Portfolio overview

HARSCO TECHNOLOGIES LLC has been granted 53 US utility patents between 2017 and 2025, placing HARSCO TECHNOLOGIES LLC at rank #6,336 across all assignees tracked by PlainPatent. This portfolio spans 46 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in E01B (PERMANENT WAY; PERMANENT-WAY TOOLS; MACHINES FOR MAKING RAILWAYS OF ALL KINDS). As a US Corporation, HARSCO TECHNOLOGIES LLC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 50.0/100 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 26 grants, compared with 27 in the 2015–2019 window — a -4% 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. HARSCO TECHNOLOGIES LLC's 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 46 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HARSCO TECHNOLOGIES LLC against peers pursuing similar technology classes.
