Portfolio overview

Yamaha Hatsudoki Kabushiki Kaisha has been granted 1,310 US utility patents between 2015 and 2025, placing Yamaha Hatsudoki Kabushiki Kaisha at rank #329 across all assignees tracked by PlainPatent. This portfolio spans 164 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in B63H (MARINE PROPULSION OR STEERING). As a Foreign Corporation, Yamaha Hatsudoki Kabushiki Kaisha is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Yamaha sits between OTIS Elevator Company (1,319 patents, rank #325) and Arizona Board OF Regents FOR AND ON Behalf OF Arizona State University (1,298 patents, rank #333) - the closest US assignees by grant volume. The composite Innovation Score of 64.2/100 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 678 grants, compared with 632 in the 2015–2019 window, a +7% 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. Yamaha Hatsudoki Kabushiki Kaisha's 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 Yamaha Hatsudoki Kabushiki Kaisha against peers pursuing similar technology classes.
