Portfolio overview

Mitsuba Corporation has been granted 263 US utility patents between 2015 and 2025, placing Mitsuba Corporation at rank #1,574 across all assignees tracked by PlainPatent. This portfolio spans 79 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Mitsuba Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Mitsuba sits between Inspur Suzhou Intelligent Technology Co., Ltd. (264 patents, rank #1,570) and Kabushiki Kaisha Toyota CHUO Kenkyusho (262 patents, rank #1,578) - the closest US assignees by grant volume. The composite Innovation Score of 53.9/100 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 147 grants, compared with 116 in the 2015–2019 window, a +27% 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. Mitsuba Corporation's 7.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 79 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitsuba Corporation 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.
