Overall rank by patents
#47,906
Across all tracked assignees
USPTO PatentsView assignee record - 5 granted patents across 6 technology areas, active 2021–2023. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H02G (INSTALLATION OF ELECTRIC CABLES OR LINES, OR OF COMBINED OPTICAL AND ELECTRIC CABLES OR LINES).
The verdict
Japan holds 5 US patents across 6 technology areas, rank #47,906 of 50,000 tracked assignees.
Japan Chain Terminal Co., Ltd. has been granted 5 US utility patents between 2021 and 2023, placing Japan Chain Terminal Co., Ltd. at rank #47,906 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.0 claims per patent with primary concentration in H02G (INSTALLATION OF ELECTRIC CABLES OR LINES, OR OF COMBINED OPTICAL AND ELECTRIC CABLES OR LINES). As a Foreign Corporation, Japan Chain Terminal Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Japan sits between JAMM Technologies, Inc. (5 patents, rank #47,902) and Jason TOYS & Electronics Co., Ltd (5 patents, rank #47,910) - the closest US assignees by grant volume. The composite Innovation Score of 39.0/100 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. Historical data spans 2021 through 2023, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Japan Chain Terminal Co., Ltd.'s 7.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Japan Chain Terminal Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Japan's 5 grants land it in the top 39% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
