Portfolio overview

Yamaha Corporation has been granted 1,296 US utility patents between 2015 and 2025, placing Yamaha Corporation at rank #335 across all assignees tracked by PlainPatent. This portfolio spans 131 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.0 claims per patent with primary concentration in H04R (LOUDSPEAKERS, MICROPHONES, GRAMOPHONE PICK-UPS OR LIKE ACOUSTIC ELECTROMECHANICAL TRANSDUCERS; DEAF-AID SETS; PUBLIC ADDRESS SYSTEMS). As a Foreign Corporation, Yamaha Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Yamaha sits between Komatsu Ltd. (1,303 patents, rank #331) and SZ DJI Technology Co., Ltd. (1,268 patents, rank #339) - the closest US assignees by grant volume. The composite Innovation Score of 60.5/100 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 653 grants, compared with 643 in the 2015–2019 window, a +2% 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 Corporation's 11.0 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 Yamaha 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.
