Portfolio overview

Koki Holdings Co., Ltd. has been granted 225 US utility patents between 2016 and 2025, placing Koki Holdings Co., Ltd. at rank #1,808 across all assignees tracked by PlainPatent. This portfolio spans 62 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.3 claims per patent with primary concentration in B25F (COMBINATION OR MULTI-PURPOSE TOOLS NOT OTHERWISE PROVIDED FOR; DETAILS OR COMPONENTS OF PORTABLE POWER-DRIVEN TOOLS NOT PARTICULARLY RELATED TO THE OPERATIONS PERFORMED AND NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Koki Holdings Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Koki sits between Parallels International Gmbh (226 patents, rank #1,804) and AFL Telecommunications Llc (224 patents, rank #1,812) - the closest US assignees by grant volume. The composite Innovation Score of 59.3/100 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 195 grants, compared with 30 in the 2015–2019 window, a +550% 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. Koki Holdings Co., Ltd.'s 12.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 62 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Koki Holdings 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.
