Portfolio overview

Hokuetsu Industries Co., Ltd. has been granted 8 US utility patents between 2017 and 2025, placing Hokuetsu Industries Co., Ltd. at rank #31,893 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 claims per patent with primary concentration in B66F (HOISTING, LIFTING, HAULING OR PUSHING, NOT OTHERWISE PROVIDED FOR, e.g. DEVICES WHICH APPLY A LIFTING OR PUSHING FORCE DIRECTLY TO THE SURFACE OF A LOAD). As a Foreign Corporation, Hokuetsu Industries Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Hokuetsu sits between Hmicro, Inc. (8 patents, rank #31,889) and Hoppecke Batterien Gmbh & Co. KG (8 patents, rank #31,897) - the closest US assignees by grant volume. The composite Innovation Score of 49.8/100 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 6 grants, compared with 2 in the 2015–2019 window, a +200% 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. Hokuetsu Industries Co., Ltd.'s 15.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hokuetsu Industries Co., Ltd. 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.
