Portfolio overview
KURARAY FASTENING CO., LTD. has been granted 22 US utility patents between 2016 and 2025, placing KURARAY FASTENING CO., LTD. at rank #13,516 across all assignees tracked by PlainPatent. This portfolio spans 24 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in A44B (BUTTONS, PINS, BUCKLES, SLIDE FASTENERS, OR THE LIKE). As a Foreign Corporation, KURARAY FASTENING CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 43.9/100 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 15 grants, compared with 7 in the 2015–2019 window — a +114% 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. KURARAY FASTENING CO., LTD.'s 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 24 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KURARAY FASTENING CO., LTD. against peers pursuing similar technology classes.
