The verdict
Yanmar holds 206 US patents across 95 technology areas, rank #1,958 of 50,000 tracked assignees.
Yanmar Power Technology Co., Ltd. has been granted 206 US utility patents between 2020 and 2025, placing Yanmar Power Technology Co., Ltd. at rank #1,958 across all assignees tracked by PlainPatent. This portfolio spans 95 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in F02M (SUPPLYING COMBUSTION ENGINES IN GENERAL WITH COMBUSTIBLE MIXTURES OR CONSTITUENTS THEREOF). As a Foreign Corporation, Yanmar Power Technology Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Yanmar sits between Noble Systems Corporation (206 patents, rank #1,954) and Heraeus Deutschland Gmbh & Co. KG (205 patents, rank #1,962) - the closest US assignees by grant volume. The composite Innovation Score of 58.3/100 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. Historical data spans 2020 through 2025, with 206 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. Yanmar Power Technology Co., Ltd.'s 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 95 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yanmar Power Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Yanmar's 206 grants land it in the top 5% 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.
