Portfolio overview

Tsubakimoto Chain Co. has been granted 237 US utility patents between 2015 and 2025, placing Tsubakimoto Chain Co. at rank #1,726 across all assignees tracked by PlainPatent. This portfolio spans 53 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.2 claims per patent with primary concentration in F16H (GEARING). As a Foreign Corporation, Tsubakimoto Chain Co. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Tsubakimoto sits between Faraday & Future Inc. (237 patents, rank #1,722) and Beijing Zhigu RUI TUO TECH Co., Ltd. (236 patents, rank #1,730) - the closest US assignees by grant volume. The composite Innovation Score of 55.6/100 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 121 grants, compared with 116 in the 2015–2019 window, a +4% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Tsubakimoto Chain Co.'s 6.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 53 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tsubakimoto Chain Co. 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.
