Portfolio overview

Mabuchi Motor Co., Ltd. has been granted 67 US utility patents between 2015 and 2025, placing Mabuchi Motor Co., Ltd. at rank #5,170 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Mabuchi Motor Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Mabuchi sits between Kyphon Sàrl (67 patents, rank #5,166) and NCS Multistage Inc. (67 patents, rank #5,174) - the closest US assignees by grant volume. The composite Innovation Score of 44.7/100 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 42 grants, compared with 25 in the 2015–2019 window, a +68% 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. Mabuchi Motor Co., Ltd.'s 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mabuchi Motor Co., Ltd. against peers pursuing similar technology classes.
