Portfolio overview

Yanmar Holdings Co., Ltd. has been granted 448 US utility patents between 2015 and 2025, placing Yanmar Holdings Co., Ltd. at rank #984 across all assignees tracked by PlainPatent. This portfolio spans 113 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION). As a Foreign Corporation, Yanmar Holdings Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Yanmar sits between THE Coca-cola Company (449 patents, rank #980) and Spectrum Diversified Designs, Llc (446 patents, rank #988) - the closest US assignees by grant volume. The composite Innovation Score of 52.3/100 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. Between 2020 and 2025 the company received 126 grants, compared with 322 in the 2015–2019 window, a -61% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 Holdings Co., Ltd.'s 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yanmar Holdings Co., Ltd. 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.
