The verdict
Mizuno holds 95 US patents across 33 technology areas, rank #3,818 of 50,000 tracked assignees.
Mizuno Corporation has been granted 95 US utility patents between 2015 and 2025, placing Mizuno Corporation at rank #3,818 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in A63B (APPARATUS FOR PHYSICAL TRAINING, GYMNASTICS, SWIMMING, CLIMBING, OR FENCING; BALL GAMES; TRAINING EQUIPMENT). As a Foreign Corporation, Mizuno Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Mizuno sits between Kopin Corporation (95 patents, rank #3,814) and Polaris Wireless, Inc. (95 patents, rank #3,822) - the closest US assignees by grant volume. The composite Innovation Score of 46.3/100 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 64 grants, compared with 31 in the 2015–2019 window, a +106% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Mizuno Corporation's 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mizuno Corporation against peers pursuing similar technology classes.

How to use this portfolio
Mizuno's 95 grants land it in the top 21% 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.
