Portfolio overview

Hyosung Heavy Industries Corporation has been granted 95 US utility patents between 2018 and 2025, placing Hyosung Heavy Industries Corporation at rank #3,809 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.9 claims per patent with primary concentration in H02J (CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTING ELECTRIC POWER; SYSTEMS FOR STORING ELECTRIC ENERGY). As a Foreign Corporation, Hyosung Heavy Industries Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Hyosung sits between Element Six Limited (95 patents, rank #3,805) and Keyssa, Inc. (95 patents, rank #3,813) - the closest US assignees by grant volume. The composite Innovation Score of 49.5/100 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 70 grants, compared with 25 in the 2015–2019 window, a +180% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign 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. Hyosung Heavy Industries Corporation's 7.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hyosung Heavy Industries Corporation against peers pursuing similar technology classes.
